70 COPO

"Original motor in your car?
Phil "

Yep, Original Motor, Tranny (Auto) and Rear. Even the carb is original. The only non original part is that someone added headers, but the exhaust manifolds were in the trunk, so before SCR9, the headers are scheduled to be removed next week. she will be back to bone stock.

Let me see what my mechanic has to say after he inspects and tunes her up, I am not the best driver, but if he gives the Ok, then we might have a race!

Now this would be great to see. Hmmm A 4.10, and a good reaction time.... Did you ever read the car craft from '70 where they drag tested a 70 Z28 and pulled a 12.9 out of it?

The weak link is always seems to be the stock driveshaft which usually fails at that point.

One of the the fastest regular road tests with the 70 Z28's were in automatics too. At this point you get your reaction time down and let the car do the rest. Road and Track ran a 14.2 with a driver and a full tank of gas. As I recall trap speed was a touch over 100.


OK. Marlin You may get what you want after all.

Rich...Most of us are crappy drivers so don't worry about that aspect of it. If it were mine I would leave the headers on it.

I agree, leave the headers on. I think I've mentioned this before but a friend on mine has a bone stock, never opened, stock cam,intake,carb etc. 1970 LT-1 out of a '70 Z-28 that was wrecked very early in it's life. He's had this motor for like over 30 years in his Corvette. He recently yanked it out and put the engine into his son's '69 Camaro with a four speed, 4.11's, and some small nine inch slicks. The car runs 12:30's and this motor is even a little tired after so many years of street driving. Those times say alot about the performance potential of that engine. That's Rat motor territory!

Marlin,

How's the deuce setup? Stock w or wo headers, cam etc?

I need to check the build sheet and see what rear is in mine.

Wouldn't a tall spoiler car be slower than a short spoiler car due to the added wind resistance at high speeds?

Stock - GM blueprint cam, carb, intake, TRW pistons, orig. rods & crank, etc..., no headers, no traction bars (will add spring clamps after the Nationals), original leaf springs, original front coil springs, and some standard Pep Boys shocks - no drag shocks, no super stock springs, no lightweight stuff in the trans or rear or anything, and E70x14 whitewalls! (and the correct, original style battery - not a hollowed out job!).

LT1, M21, and 4.10's

OK,
Looks like mine has "GY4 = 373 Rear Ratio and "G80" = Posi

Rich,

Most cool! Gotta love the LOS cars. Build sheets are great.

3.73 is just like mine. Based upon the road test data from 1970- Even with a nearly perfect reaction time your 1320 ET's (stock with a 3.73 gear) are gonna be likely only Mid 14's..

Rich I gotta tell you If you decude to run it - a couple of passes at a local strip in your area will tell you for sure!

Ok Marlin how much would you be willing give up to even the race?? How about leaving the headers on the Z??
