70 LT-1 how fast

[COPO427]

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 He blew the motor buzzin it to 8 grand all the time with that gear - imagine that

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

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.

Here's the link, Chuck. This 'Vette flies, I watched it run during the June race last year, amazing - on belted tires. You can read the 'rules' section of the PSMCDR site, and see the differences vs NHRA. These PSMCDR's are true 'stock', especially when they are 'Certified'.

I may be slow, but, everybody starts somewhere I'd be happy to race a red/red '70 chevelle

-------January/February 1970 I bought a new LT1 Corvette roadster. 4:11s, close ratio. With about 2000 miles, yanked the smog and put a set of OK sides on it. Then borrowed a pair of slicks. Cant remember how tall they were but couldnt have been over 8 inchs wide. Went to Palm Beach Dragway (pre Moroso) and ran a 12.91 thru the traps in 3rd gear at about 7200/7300. Never so much as touched either the distributor or the carburetor! Man that Vette would run!............Bill S

Our Pure Stock is a lot like how NHRA's "stock" used to be back before they turned it into Super/Stock and S/S turned into skinny tired Pro Stock cars...it's interesting to pick up an old NHRA rule book and see just how stringent the rules *used* to be...at one time, NHRA stock actually was STOCK!
