How did you shift, steer, and hold the camera, with only two hands? [img]<<GRAEMLIN_URL>>/naughty.gif[/img]
Most impressive, Sir. [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img] |
Re: Chevelle updates
The chuckling camera-person is (obviously) my lovely assistant Rachel.
I still can't get over how well those M/T Drag Radials work. With the Polyglas', the car would've been sideways 1/2 way through 3rd gear. The Mickeys dead hooked from a 1st gear roll and only produced a chirp going into 2nd. I still want to put a few more miles under it's belt first, but I'm gaining confidence that a trip to the track just might happen before too long. BTW, the prepped heads are supposed to ship out today. |

Re: Chevelle updates
I pulled the video down. I wasn't planning on leaving that up too long anyways. I'll try to put something up later that's a little less...shall we say...<span style="font-style: italic">incriminating</span>.

Re: Chevelle updates
Remember to always put in the word "allegedly" in front of everything. That's how the media gets around it. [img]<<GRAEMLIN_URL>>/naughty.gif[/img]
Your alleged video was allegedly most enjoyable. Next time just title it <span style="font-weight: bold"><span style="font-style: italic">"Tesla All-Electric Converted Chevelle With Added Realistic Sound Effects"</span> </span> |
Re: Chevelle updates--drumroll please...
OK...after nearly 9 years of blood, sweat and gears, after more money than I dare tabulate, after more ups & downs than I can begin to count, it looks like a trip to the digs is finally on the horizon.
I have a friend who's volunteered the services of his trailer and a brain bucket. All I've left to do to the car itself is get the driveshaft safety loop installed, I *think* I've got everything else covered. We just got off the phone, and weather permitting (and providing I can get the loop installed in the meantime), tentative plans are to take the car to Kil-Kare on 8/27. I've never been more nervous about taking a car to the track in my life. [img]<<GRAEMLIN_URL>>/eek.gif[/img] Stay tuned for updates. |

Eric, I don't you if you have purchased your driveshaft loop yet but I've always been a fan of these Metco units. They're tailored to the floor pan and look a little nicer than universal ones that have 50 bolts in them!

Re: Chevelle updates--drumroll please...
I do have an Allstar unit on hand, just have to figure out how to squeeze it in there next to the X-pipe.
|
Re: Chevelle updates--drumroll please...
No go on the Allstar. There isn't enough room to squeeze it in above the X-pipe, plus the ID is barely big enough to clear the 4" driveshaft, there's no room for the fasteners.
Looks like I'll be ordering a Metco, UMI, BMR or building one from scratch. |
Re: Chevelle updates--drumroll please...
I've heard of people making them out of old compressed air/gas tanks with a chop saw. Just make sure it's empty with the valve open before you start cutting!
|
Re: Chevelle updates--drumroll please...
Update to the track date: We're planning to go this Thursday the 20th weather permitting.

After a little finagling, I'm happy to report the operation was a success. The car now has a driveshaft safety loop, and I <span style="font-weight: bold"><span style="font-style: italic"><span style="text-decoration: underline">barely</span></span></span> managed to snug it up to the NHRA minimum spec of 6" from the front U-joint. It's a good thing I ordered that Metco unit with that big-ass 6 1/2" hoop--at the tightest point, there's about 1/2" of clearance to the driveshaft. Off to look for a helmet later this evening. |
Re: Chevelle updates
Good deal, Eric! Looking forward to hearing about your dragstrip outing soon.

Re: Chevelle updates
we want video!

Re: Chevelle updates
Take a look at the date inside the helmet first....they sell new helmets that are already 3 years old. And they check them at the track
|
Re: Chevelle updates
I remember you mentioning that--as I don't have a rule book, I'm a little confused on exactly what I need helmet-wise. My friend who's taking me down said a DOT helmet will suffice, i.e. a good motorcycle helmet. If I'm going to spend the $ on one, I need to make sure I get what I need and will keep the tech guy happy.
(obviously I wasn't able to pick up a helmet tonight) |
Re: Chevelle updates
Found the NHRA helmet rules. Reads like a bowl of alphabet soup.
|
Re: Chevelle updates
I once asked about buying a helmet and which one to buy. I was answered with how much is your head worth? Bought the best availabe ...Right or wrong, made sense at the time.

Re: Chevelle updates
I *think* I've got the requirements figured out, now it's a matter of (A) choosing a helmet, and (B) FINDING one. There's nothing local, it looks like I'm going to have to make a road trip to Jegs and buy one in person if I want to make sure it fits and don't get stuck with a "NOS" (sic) one.
The motorcycle helmet isn't an option, it has to be Snell or SFI rated. |
Re: Chevelle updates
Eric...make sure it has the current Snell rating...the 'tech boys' can be a pain about headgear [img]<<GRAEMLIN_URL>>/rolleyes.gif[/img]

Chevelle track results
Could've been better, could've been worse.
We didn't get there until around 7:00--my trailer guy didn't get off work until 5:00. We were loaded up and hit the road a little after 6:00. Of course the track was pretty busy as the weather was very nice. Anyhow, to get to the results. I planned on taking it easy and just wanted to get a feel for the car on the track. I only got two passes in. The first was 1/8 mile only, and they forgot to reset the tree back to full from a Pro tree (for the vehicle that ran just before I did). I didn't even do a burnout. I drove around the water and snuck up to the starting line--it's been 20+ years since I've been down a dragstrip, cut me a little slack. I staged, brought the rpm to ~2500 and launched the car. Much to my surprise, it dead hooked. I stayed at ~1/2 throttle until the car rolled out a bit and hit it, shifting at 6K. 60': 1.761 330': 5.033 660':7.748 @ 90.27 mph. Using the standard 1.56 correction from 1/8 to 1/4, that would've been roughly a 12.07 pass. I quickly got back to the staging lanes and was able to get another pass in roughly 1/2 hour later. Since I figured I wasn't going to get another pass in (they close the lanes @ 9:00 and it was almost 8:45 when I made my 2nd pass) I decided to run it out, and I wanted to try the launch a little harder. Again, no burnout, just drove to the line. I bought the tach to ~4000 and launched, and the car blew the tires off. I backed out and hit it again and it hooked, grabbed 2nd, then went for 3rd and my friggin' hand slipped off the shifter knob. I got it into gear and drove it the rest of the way down and backed out just before I got to the traps. 60': 2.205 ( [img]<<GRAEMLIN_URL>>/rolleyes.gif[/img] ) 330': 5.498 660': 8.369 @ 88.22 mph 1320': 12.73 @ 111.28. I left at least .6 on the table just in the 60' time. The difference between the two 60' times was .444. The rule of thumb is what you gain/lose in 60' you multiply by 1.5 for the 1/4 e.t. That's .66 seconds, which would've also been a 12.0 pass, not taking into account missing 3rd gear. The car has <span style="font-style: italic">easy</span> 11's in it as it sits...but the driver needs a <span style="font-weight: bold">LOT</span> of work to get it there. [img]<<GRAEMLIN_URL>>/frown.gif[/img] But....that and a Lincoln <span style="font-style: italic">might</span> get you a cup of coffee at your favorite coffee house...until it prints it on a slip, it's all just speculation. I'm waiting on video via email. I'll post it as soon as I can. More soon. |
Re: Chevelle track results
Sounds like you had a blast! [img]<<GRAEMLIN_URL>>/burnout.gif[/img]
|
Re: Chevelle track results
I did, I just wish my driving skills weren't so rusty. I had an easy 11 second time slip in the bag and I blew it.
I'm hoping to get the car back out there again soon, maybe within a month or so. |
Re: Chevelle track results
Two videos are now up on Facebook.

Re: Chevelle track results
You'll get there and on the positive side, you brought home an unbroken car from its first track visit which is alway a good thing. Looking forward to hearing about your next strip visit.
|
Re: Chevelle track results
Awesome Eric. I'm glad to hear you made it. Won't they require a rollbar if you go sub 12's?

Re: Chevelle track results
The formal cut-off is supposed to be 7.49 in the 1/8 and 11.49 in the 1/4. SOMETIMES They'll give some leeway.

Re: Chevelle track results
The "Hook" is set..........LOL..........Enjoy and keep the reports coming !!!!!

Re: Chevelle track results
Sorry, but I'm a little confused trying to follow this thread??
Here's what I THINK (??) I got so far: 1. Do did a GREAT job restoring the Chevelle. It's a BB 496 you did, and stick. Confusion starts with: 1. It's a 496 that you did a separate "build thread" on. You linked it back a few times. BUT that thread say "Remember, the results up to this point are still with 100% original, UNPORTED cylinder heads with stock 2.19 1.72 valves." 2. In the update thread you go on to say you got 840 casting in 2 weeks and of to Chad for porting as shown in the picture. Page 11 3. See on page 13 that Chad got some nice results out of the 840's. 4. Never got it back to the dyno? 25 pulls on it with stock heads and NOTHING to figure the new heads????? I missed cam timing so cant say what I figure the heads help was, say 70hp?? So a 670 hp motor and only getting 12.0's or high 11 with a Mt 275 Dr tire (which by the way probably has the most advances as any tire today for racing)??? I thought hat car should have been over a second faster. My '69 Nova set-up like this (M21, 4.56, 9" slick) but with a lil mild 396 went 10.47. Basically a STOCK balance L-78 STANDARD bore 402 with only ARP rod bolts. Stock pan, PORTED 840's, but did have a strip dom intake and reworked holley 800. UT I did have a solid roller .660 cam. Seems like you know what your doing, and been around these cars for a while, but what are we missing??? John |
Re: Chevelle track results
(1) 496 is still running with UNported heads--just received new heads from Chad, haven't gotten them installed yet. Motor made just over 600 on the dyno (30 pulls) in current form.
(2-4) Heads aren't even built yet, will be built and will go back to the dyno shortly. First, remember this is a NEW combination that's only been down the track twice. First pass was an EASY pass and went 7.74 @ 90+ with a soft launch and short shifting. That equates to ~12.07--again, on a soft pass. It only 60'ed 1.76. The 2nd pass blew the tires off losing over .4 in the 60' AND I missed 3rd gear. I just drove it the rest of the way down the track, still went 12.7 @ 111. Both runs were also with cold tires--I didn't even do burnouts, just wanted to get a feel for the car on the track. Like I said, the car has EASY 11's in it as it sits, it's the DRIVER (me!) that needs work. I haven't made a pass down a dragstrip in over 20 years! Give me some time to get the hang of this again and to get the car shook down. There's <span style="font-weight: bold">plenty</span> left in it! |
Re: More Chevelle updates
Eric, Man it's great to see you have so much enthusiasm for getting your combo dialed in! My get up and go...got up and left.
Please update us all on you combo [I've sure it's listed more than once in the 55 pages .. 496 4 speed I know..[true 496 or 489?] Carb? Gear? Intake manifold? Distributer?

Re: More Chevelle updates
First pass--I wasn't expecting it to hook, took me a bit by surprise:
http://i33.photobucket.com/albums/d7...psn12otl7n.jpg Compare to 2nd pass where you can clearly see it blew the tires off the line. Also note the track guy mopping fluid from my lane from the car before me: http://i33.photobucket.com/albums/d7...psx2xu4k3v.jpg Alternate view of 1st pass: http://i33.photobucket.com/albums/d7...pso2ehvrxk.jpg Alternate view of 2nd pass--note the car nose over about mid-track...this is when my hand slipped off the shifter causing me to miss 3rd gear. I stuffed it back in gear and drove it the rest of the way down: http://i33.photobucket.com/albums/d7...psekbfo4b1.jpg Time slips: http://i33.photobucket.com/albums/d7...psydg3usa2.jpg |
Re: More Chevelle updates
If memory serves me the 291 and 840 heads are semi interchangeable [except maybe for the spark plugs..one was a small plug if I remember..] I think they CC'ed within 1 0r 2 CCs...
Are you thinking maybe you'll need a bigger, better intake manifold with the ported heads? Any reason you went closed chamber in the original build? |
Re: More Chevelle updates
I have several intakes I can use, but I'm planning on staying with the stock 163 as I don't think it will be much (if any) of a restriction on this build. I've already tested a heavily ported Holley Strip Dominator on this engine (during the last dyno session) and the power differences were low single digits.
Why I chose closed chambers--I wanted to see what I could do with them since everyone's always so quick to dismiss them. |
Re: More Chevelle updates
Oh snap! I didn't realize that you had the infamous Crane #131311 camshaft in that motor. Crane really hit onto something with that great camshaft and Ive known many cars that have flown with it. One in particular was an early Camaro , crate LS6 with that exact camshaft that spit out 10.60's.
