68 Yenco clone

Hello once again....

The L72 heads were closed chamber, rectangular port, cast iron jobs. I can't comment about the L88 in a 1968 Yenko. I suppose there's a chance one might have been swapped in.

This is a bit of a commercial [img]<<GRAEMLIN_URL>>/wink.gif[/img] , but in an upcoming issue of <span style="font-style: italic">Muscle Car Review</span>, you'll see an article I wrote on what to look for in a clone (it goes both ways here -- for the guy who hates clones and for the guy who wants to build one). It's called &quot;Clone Wars&quot;. I don't have a cover date, but when it hits the newsstands, it should help point you in the right direction.

Take care man.

Thanks Bob,

The guys here have been a big help and my thanks again to Wayne and I will read his article coming up in Muscle car review magazine with interest. This has always been a touchy subject as for the purist there is the original and the original only and I can understand that. My thought is that the quality of the car remains long after the conversation on real or fake has stopped.
The questions I am asking have surely been asked a thousand times and I suppose I am just after a basic list of do's and don'ts for the 68 Yenko.
It is not a numbers car but, unless you looked hard it would be hard to tell, is what we want here.
So without looking at stamping # on housings and distributors ect, what, in your opinion would be a walk up necessity for a Yenko??

Wayne,

Thanks again for clarifying the cyl head deal as it turns out I have a pair of closed chamber rect port cast heads (same head but 2 different p/n) and actually wanted to swap them for some open chamber heads for another project. Now they are the start of an L72 I hope.

Cheers Mate: Chris H

Glad you're on track. You and I are on the same page when it comes to original and clones. I for one will never have sufficient $$$ to buy an original, even though I pine for one. That makes clones the only reasonable option. I think you'll have a nice hot rod! And as far as I'm concerned, you can keep asking questions. If can answer them, I will.

Catch ya' later.

Wayne or Bob,

Did the 68 Yenko come with a 140 MPH speedo or was that just 69

and what about things like power steer, air and power windows, I know they came on SS and RS but did they come on a 68 Yenko

Cheers: Chris

chris, 68 yenkos had 140 mph speedo's, mine had no P.S. as allthe other ones kline chev sold in 68, also no ac, nopower steering all were ss's 4 speeds. you should really get rid of the auto. trans. They had passenger car engines ( L 36's, low comp. 10.25 to one,hydro lifters small carb,small heads, small intake manifolds, mild cams.) the factory rating wae 390 H.P. which was very high. Had this motor in a 69 vette. absolutly no where to go, to up H.P. You want a L 72 4 speed 100%. As to clones , yenkos new, were the biggest clones of all, think about this and reply. thanks Bob krueger

Bob,


Are you trying to say the cars that Yenko converted came from gM with L-36 engines???

[PeteLeathersac]

As I've always understood, all '68 Copo 9737 cars were shipped w/ the unique MV Suffix 396 L78 engines installed and planned for Yenko to transplant 427/425 L72 shortblocks reusing the heads etc..
* Note not all cars were converted and some were sold and/or dealer traded w/ their MV Suffix L78's still intact..

Can anyone post the unique carb #'s shipped w/ these MV Suffix L78's?.
Also what was the factory HP rating of the MV Suffix L78's?.

Bob,

From what I am reading 1968 was a mix of corvette engine transplants and later that year the COPO 9737 and all 69's were COPO
Even though the torque drive was an option, it was never in a Yenko as they were all 4 speeds. I am hearing a lot were L78 396
and L72 427 and they had the same cyl head cast rect port closed chamber.(I have 2 heads #3964291 &amp; 3873858)can someone tell me which number is correct for 1968.
Now what about the L88 427 ??? is there a 1968 L88 Yenko

Cheers, Chris
ps; thanks again , someone said this would be hard and they were right.
