Re: 68 Yenko clone
 

Wayne, close but not accurate.This is from chevrolet, ZLX, 12.25 comp. L 88, ZL1, hybred.Iron block, alum. heads. In house use only, not sold. motion no thing to do with this motor.produced from late 60's to around late' 90's(chev alittle hazy about end date) only used for experimental purpose. end of the line for hi perf. 427's. most H.P. of all but unreliable. From chevrolet, also l-36 , desighed as a big block of medium H.P. for the use in the heavy sedan;s coupes they planed to build, and also as a motor for med. duty trucks, because of the broad torque band. Used to work for chev. back in the 70's, 80's. had chev monte carlo demo's 454, 345 H.P. chevy also used med H.P. 427,454. motors in there own brand of motor homes, in the 70's. remember those? Those were the days my friend , we though they would never end but. Thanks Bob krueger

Re: 68 Yenko clone
 

Bob,

I think your info may be a bit incorrect. the ZLX was installed in Motion cars. It was also availble to all buyers over the counter.

I also believe all 68 Yenkos started as L78s. 67s were available as 390HP.

There are many sharp cookies on this board. Try to back up your statements with facts.

Re: 68 Yenko clone
 

chris,


The 858 Heads are 66 and the 291 heads are late 69-70. Although both are closed chamber rectangular port heads, you will need 840 castings to be correct for a 68.

Re: 68 Yenko clone
 

My info came straight from chevrolet, the complete motor was never put on the market unless the history depart. has slipped a gear? Never heard of a car with that equipt, back in the day? chev stated that research was done on types of that motor till the 90's. the add could be what the industry called a teaser, to test the market for aproduct.AS 1970 was the last year for the high H.P. motors. as the ad reads that motor would have way over 700 H.P. Any info about a real ZXL car? Thanks Bob krueger. motion was the seller, not the producer in the ad.

Re: 68 Yenko clone
 

Pete,

Can we agree that there were 70 Yenko Camaro's built in 1968 and that all were 4 speed.Most were SS and at least one of the first COPO's was an SS/RS L78 (396-375hp)
That said,I am hearing that of those 70, 64 were COPO 9737 but in the initial months of 1968 6 were transplants with a COPO option
Can someone confirm this bit.

Re: 68 Yenko clone
 

This thread seems to be heading in many directions of facts mixed w/ well intended but some seemingly misinformation?.
But please carry on as a few things may result as true but previously unknown...like a '68 Gibb Copo Nova trans in a 68 Copo 9737 Camaro, stranger things have come to light before so why not?.

Back to the '68 Yenko cars specifically and nothing to do w/ the '67 or '69 cars, here's what I understand as true;
Although there may've been a few exceptions, the '68 Yenko's Camaros were built from Copo 9737 cars factory shipped w/ the largest engines in place being the unique MV Suffix 396 L78..
These were in place and operational but planned for Yenko to remove and transplant 427/425 L72 shortblocks reusing the heads etc off the MV engines..
* Real '68 9737 Camaros are identifiable by the MM Trim Tag also some of the previously mentioned options including the 140 Speedo..
** Again not all cars were converted and some were sold and/or dealer traded w/ their MV Suffix L78's still intact..
*** Some cars could've been transplanted w/ L88 or other engines..
**** 9737 cars could've been and/or were shipped from the factory to other dealers and not just Yenko..
***** If production of '68 Yenko Camaros is known, is it confirmed how many were 9737 cars and of that sold as converted or unconverted?.
Plus is production of the '68 9737 cars absolutely known...especially if other dealers recv'd 9737 cars!?

Again can anyone post the unique carb #'s shipped w/ the MV Suffix L78's?.
Also again, has the factory HP rating of the MV Suffix L78's ever really been confirmed as 375 like a 'regular' L78?.

Re: 68 Yenko clone
 

Pete, you make a nice summation and some good points here.

At the end of the day, this is a clone we're talking about. He's been told the possibility of blocks &amp; heads used in '68 Yenkos several times now. As you state, only certain things we know, but there are other possibilities. The safest bet is to drop in an L72 and be done with it.

If you want the 'most correct' clone, build on what we know. Not what might or could have been.

Re: 68 Yenko clone
 

Bob, per your request myself and Dana sent you something the day before yesterday and I also sent you an email and am still waiting for a reply. Was this a bait and switch?

Re: 68 Yenko clone
 

I know Chris is only cloning around but since the facts were getting lost in the haze I thought if we all laid what we knew on the table perhaps more could be confirmed or dispelled also a few new facts or possibilities may come to light?.

Re: 68 Yenko clone
 

Pete, Bob Wayne and all who have helped weed out the basic facts

I am now where I want to be with this and know a pantload more than I did last week.
I found this article about the #8021 and it states from the current owner &quot;For 1968 the 9737 COPO comaro was only available to Don Yenko and in fact Yenko was considered the manufacturer for these 68 Yenko Camaro's. However this #9737 COPO package was added in 1968 as per Don Yenko's request to RPO L78 SS Camaro's that were equipped with the 396/375hp big blocks.
The COPO #9737 designation added for 1968 cooling, suspension and brake upgrades along with a 140mph speedometer, heavy duty springs, larger anti roll bar, M21 tranny and a 4.10 posi rear diff. These 9737 COPO's 1968 camaro's were delivered from Chevrolet to Cannonsburg with RPO (regular production order) L78 396/375 hp engines. Yenko's mechanics then removed the L78 396 engine and installed a L72 short block. The original L78 heads and aluminum intake and carb were then installed on the L72 short block.&quot; end quote. author unknown, but pulled from the Las Vegas Clasic cars website.

I would assume this to be correct and still leaves 6 cars not known from the 70 ordered As far as the comment about why not auto's is not a strength issue (as I have put 1200hp through a T400) its just that they all came with an M-21.

Cheers: Chris H

ps: Great site great ppl my thought for the week!!! never kick a fresh turd on a hot day!!!!

Re: 68 Yenko clone
 

Tom,
You are right, and I think this will be a tribute to the 68 Yenko moreso than a clone we wont chase part numbers but the part itself we will try make right.
ie solid L72 cam, closed chamber iron rect port heads, 427 block ect. I will keep posting the build pix as the body goes in to paint as we speak. Thanks again for your input.

Re: 68 Yenko clone
 

Guys,

One thing I forgot to ask was the color, was Yenko particular about the color ordered or were they a mix of all colors offered in 1968 for the Camaro. My hunch is this will go Matador red and was the stripe painted on or a decal.?????

Cheers:Chris H

Re: 68 Yenko clone
 

Respectfully to Tom, as to your last post, all my info, is from chev, or the car's themselves. I take the info I gave on R.E. 68 yenko clone, with my first hand info, having owned and raced a new 68 yenko for 2 years, and I don't joke about it. What 67 69 chev 427 hydro lifter engine had 410H.P and 425H.P. what was the L numbers? yenko rated them at that. yenko also over rated all his engines. A 68 69 l72 at 425H.P. became 450H.P.most pro. racers ,quater mile, used 4 speeds, as I did because they were faster.Never came close to losing to one, refer to original feature car, dec 2004, and first place winner stickers on rear window. NEVER lost in 2 years, my camaro was 8016# And I stand by my statement that all 68 yenko's should have been 4 speeds, auto cars had hydro lifter motors and were much harder to modify, and had less factory H.P. I worked for chev, on the dealer level from 72 to78, and also got a lot of my info from the factory people, As I was at manger level. chev, still stands on they facts about the zlx 427, that they never sold parts or motors, right or wrong, as they were not allowed to.(no medium sized cars with over 400 C.I) but they did, thats what yenko was all about.To Jason and Wayne Iam sure there are sharp cookies on this site, but how old are they, did they own one of these cars in the day, when new, and did they modify them and race them as thats what they were for? Or do they just read second hand accounts, and books? I did it in 68 69, for real. How many on this site have done that? Sharp cookies are good , not alway's right, as no one is, but they are hard to swallow. Thanks for listening, my yenko was my 6th muscle car. and the fastest by over 3/4 second. Bob Krueger.

<span style="color: #FF6666">
My point was not to say a auto would our run a stick car, too many factors to consider there, but simply to state that in ’68 GM had a very solid auto, which in ’69, coupled with the same L-72 solid lifter engine as the 4 speed car got, was a very good combo. Even today, with better street tires, on the street, the auto will run with the stick car, due to traction issues. I say this not from reading books, but from first hand knowledge of racing a 1969 Yenko (auto) for 13 years in factory stock trim. On the strip, with slicks, then the stick has an advantage. Even then the stick car better be darn consistent, as our car is, or ???

As per my expertise, and where I got my information, here goes. A. from a large stash of original Yenko paperwork, B. as founder and president of the Yenko Sportscar Club and Supercar Registry, I have been fortunate enough to get to have numerous conversations with original owners, former employees of Yenko and former employees of Chevrolet (including Jim Mattison), C. as host of the Annual Supercar Reunion, I have been up close and personal with many, many Yenko built cars, many on the drag strip D. for the past 13+ years myself and son Rob have actively been racing a 1969 Yenko Camaro, auto, in the Purestock drags as well as numerous nostalgia events. In addition, I have played with several other interesting cars (in the early '70s a '69 Z-28, last few years Red Alert LS-6 Chevelle, survivor L-78 '69 Camaro 4-speed, dealer installed 427 '69 auto Chevelle, etc, ) and a few other Yenkos, ranging from a Stinger Corvair to a SCCA Roadrace Camaro to a 1969 427 Yenko Nova, am presently redoing a ’69 Yenko Chevelle, a ’71 Vega and a ???

Re: 68 Yenko clone
 

Hi Bob.

Before you start questioning some of our ages and equating that to knowledge, you should perhaps do some research. Or ask. Plenty of us have (considerable) racing experience, and plenty of us are old enough to have first hand experience in the era you’re speaking of. Chevrolet openly sold pieces to build the ZLX. It was no secret. It was simply an L88 with iron heads. If you scroll upwards a page or two, you’ve been proven wrong with regard to the ZLX and I still maintain you’re wrong about L36 passenger car engine use in Medium Duty trucks (which for this site is considerably off-topic). Your errors here are beginning to cast a shadow on some of your other statements. And if we’re all collectively wrong and you’re right, the onus is upon you to prove us wrong. Provide us with real facts backed with hard documentation. Otherwise, your entire first hand story is beginning to sound a lot like faded memories, wishful thinking and most likely an abundance of conjecture.

Basically, I call BS.

Wayne Scraba

Re: 68 Yenko clone
 

Also to add to what Wayne has said...there is an original owner of a ZL-1 Camaro on this site...and also an original owner of a 1969 Yenko Camaro as well...

See these features:

https://www.yenko.net/ubbthreads/ubbt...332#Post168332

https://www.yenko.net/ubbthreads/ubbt...436#Post202436


So, yes, there are a few that &quot;were around&quot; at the time.

The features also make for some GREAT reading I might add! [img]<<GRAEMLIN_URL>>/beers.gif[/img]

Re: 68 Yenko clone
 

And do not forget Ray Morrison, who just happens to be an orignal owner of a 1968 427 Gibb/DH Nova, who paid for his car drag racing. BTW, a factory L78/AUTOMATIC.

Re: 68 Yenko clone
 

Gentlemen and cookies, I think it's great to agree to disagree. wonderfull? And I am glad that there are more original owners still out there, I feel old enough as is.I do think that its importent to know what 427 engine yenko put with his auto. trans. camaros.? What 427 chev. engine. hydro lifter, app. 400 h.p. from chevs ratings, is it? What L#, can anybody tell me,the only one chev listed then and now is the L36 390-400, 4barrel, 3,2;s, chev rated H.P. Had one in a 69 vette ,390 hp. 4 barrel, 4speed, almost no where to go to add hp. As to proof of the chevy fact's on the zxl or L36, just google it up , almost to much info, those are FACTS from the manufacture, and Wayne zxl had alum. heads look it up, if there's bs,its on the bottom of your shoes. AS I said for proof, just look up on this site, feature car dec 04, and read the repleys and look at the pictures.I am the good looking guy in picture 1, with the sunglasses, white t shirt, holding the first place trophy, next to the green yenko.(northstar dragways Mn. 1968. thats proof!) The guy I gave those pictures to and about 25 other's never returned any, 2nd owner after reso. I think. If theres any question on any thing I have said, I would certainly answer then and were I obtained the facts. I do not BS, dont need to. have not been around muscle cars for a long time, moved on to airplanes after my retirement. 36 years in the car bussines, most as used car manger, started with chev in the early 70's, just a few years after yenko build his 70 nova's. And I had a lot of talks with those men in the R.and D.dept. and 2 had worked on the project that put the drivetrains in the yenko and other's car's, that only about 3 years after the cars were built. I have more info .on the yenko project, but first we have to settle down the doubting thomas's . People on this site like to list the cars they have had, so here goes 1, 1962 bel air red coupe 4speed 409 2 4 barrels. 2,1963 chev biscayne 2 door post , silver, 4 speed 327 340 hp,390 rear end. 3, (my favorite) 1965 pontiac gto post, red,tri power 4 speed 360 hp ,370 rear end. 4, 1966 chev. vette convert, blue, white top327 350 hp. 5,1967 chev corvette 427 l71 3-2's 435 hp.maroon, t top.6, (only new oneI bought) 1968 chev yenko camaro, green, 4 SPEED,ys 8016# 450 hp. builtd up to over 600 by me and a friend. 7, 1969 pontiac GTO, 4 speed 400 350 hp dark blue same int, hood tach. ralley wheels. 8,1969 chev vette 427 390 hp(L 36 thats the one I talked about)8, bought in 1981, 1970 chev z 28 LT1 360 hp? 350,
4 speed ,red, black, stripes, ralley wheels. nicest driving chev I had, but not the fastest. And about 4 other ones that I bought as used car manager, for wholesale and sold for retail a short time later 1,1970 ford torino g.t.? orange, large black stripe down center of car,hood scope attached to carb big block 390 428 429 not sure, it was a ford, didnt pay it any attension.2, 1970 chev vette coupe,very low miles, 350, 300 hp. 4 speed charcoal, aqua int.3, 1968 olds 442 dark blue, 4speed,350 hp. texas car.4, 1967 pontiac. GTO blue 4 speed 400 350 hp. ralley wheels. well thats enough you get the picture. Now who can come up with the L# of the 427 hydro lifter motor, 427, that yenko put with his 67 and 69 camaros, that had around 400 chev, rated hp. And I do take remarks like I was wrong, very well, thank you Bob krueger

Re: 68 Yenko clone
 

Hey Bob…

I don’t see anything in your prattle that looks anything remotely close to hard evidence of fact. It’s all personal chest beating and braggadocio. You might be able to fool the fools in some places, but I’m quite positive you won’t get far with this crowd using those tactics.

For all intents and purposes, you’ve called me a liar for doubting your convoluted version of fact and not taking everything you say as Chevy gospel. That sir is pathetic. I suggested you prove what you’ve stated by way of hard data. I haven’t seen anything from you other than rambling self promotion. And after reading the above tedious retort from you, it all looks rather like make believe.

Re: 68 Yenko clone
 

Belair62, you are right, the drivetrain came from a vette about the same vintage, that was totaled, my high school friend, named brian mcabe did the switch, and later sold the car , to me, not sure the year of the vette, but I think the top hp. on a 327 vette that year was 340. Bob krueger

Re: 68 Yenko clone
 

For 1969, GM installed the L-72 427 solid lifter engine in both 4 speeds and autos, Camaros and Chevelles, known as COPOs, not only for Yenko, but other dealers as well. Not for sure what reference material you are using, but this is well documented in almost all reference materials dealing with high performance musclecars.

Here is a Yenko ad from 1969, listing the 427, 450HP as available with either 4 speed or auto.

Re: 68 Yenko clone
 

wayne, finally an real question, my mistake the removable top panels, were on my 69 vette, and as I also remember the 69 had factory side pipes. Instead of personal attacks why don't you answer the questions, I asked before like the L# on the camaro 67 69 hydro lifter 427. If you google chev on the zlx motor you will find all the info I gave you plus more. what else would you like to question? Bob krueger.

Re: 68 Yenko clone
 

Geez...I cannot tell you what the L# would be for a hydro 427 Camaro in 1969, as there was not a hydro lifter 427 available for Camaros in 1969. All 427 equipped 1969 Camaros got the L-72.

Re: 68 Yenko clone
 

Bob.

There was no hydraulic lifter 1969 427 Camaro. At least in my universe. And I suspect the one most other people on this site are from. And I'm not the one who should be supplying documentation to back my stories. You should. And by the way, I sure wouldn't be calling a public researched online encyclopedia like Wikepdia a source of reliable hard data for musclecars.

I'm still waiting for real documented Chevrolet data from you Bob. You started this. Now finish it.

If you like camaro,get this magazine, it's all about only 69's, it also states the car to have hydro. lifters? I went so far as to call the editor about amonth ago they said the articule was correct. call them camaro milestones 17757 u.s.19 north#475 clearweater Fl.33764 phone 727 712 0035 editor Katie Boyer.I saw on this site an yenko add, 67 camaros auto, trans, 427, 410 hp.? the add was from 67. also can send you this copy of magazine if you like?
