70 LT-1 how fast
 

Here's something some of you may find interesting. Especially you deuce owners. In the very early seventies a friend of mine bought a LT-1 out of a wrecked 1970 Z-28 and put it in his corvette. A few years ago he put the motor in a 1969 Camaro with a 4 speed, nine inch slicks, headers and 4.11's or 4.56's. Now this motor has never been opened up and retains the original, camshaft, intake manifold, and 780 Holley. Anyway the thing runs 12.30's but I forget the MPH. I think that's really impressive and says alot about the performance potential of these engines. Correct me if I'm wrong but I want to say that in the 70 Corvette the LT-1 was more expensive than the LS-5 454.

You're right.
The 1970 Corvette with a:
ZR-1 was $968.95 MFR's suggested-Dealer Price $699.20.
LT-1 was $447.65 MFR's suggested-Dealer Price $323.00.
LS-5 was $289.65 MFR's suggested-Dealer Price $209.00.
L-46 was $158.00 MFR's suggested-Dealer Price $114.00.

Nice Engine!!---The pizza parlor where I use get my daily nourishment from back then ,the owner's son had picked up one in '70---really a sweet engine combo, --I don't recall the name of the color right now--Burnt Orange?

Mostly Mid to low 14's stock in the 1320. The more gear the better for the LT-1. Engine was very responsive to modifications. Car Craft did the typical day 2 modifications in a 1970 issue, on a 70 Z-28.

As I recall, they reworked the spark, re-jetted the Holley, put on headers and slicks. The result was high 12's and a broken U joint shortly after.

If anyone has this issue of Car Craft, I'd be interested in a copy if someone could scan it and email it to me.

Those times are absolutely believable. In 1973 thru 1975 I had a 69 Z28 with the LT1 engine out of my 70.5 Z28. I had the optional off road '140' cam, an Edelbrock Tarantula intake and a 750 Holley double pumper. Remainder of the engine was factory stock. Ran a 4.88 gear behind an M22 and the car ran consistent 12.0's with an occasional dip into the high 11's. Had a lot of fun on the street with it too! The guy who wound up with it put in a 5.38 gear and got down in the 11.80's https://www.yenko.net/ubbthreads/imag...emlins/eek.gif He blew the motor buzzin it to 8 grand all the time with that gear - imagine that https://www.yenko.net/ubbthreads/images/graemlins/no.gif

Mark,

I will see what I can do. Depends on the quality of my scanner.

The real proof is at the Pure Stock Drags in Stanton, MI!!

As in: Sept. 2004, Benoit Holloway from Marion, LA, 1970 Corvette with an LT1, 4sp, with 4.10 gear: 12.574 @ 112.50MPH !!!!! The car is Certified Stock too https://www.yenko.net/ubbthreads/imag...emlins/eek.gif

I just want to tell MY real factual expereince. After returning from Vietnam, I ordered a 70 Z-28 with Turbo 400 (in the tree) with 4:10 gears. Over time removed all the SMOG, Mods to stock 4555 Holly, Recurved Dist, Tarantula Edelbrock, Hooker Headers, Hurst Line-Loc, Stock Long Block, Stock T-400 & Convertor and small (??)Racing Slicks.
High 12's.....maybe not impressive sounding, but in the day, was quick.
