I believe that the camshaft rules would have been roughly the same for a Stocker in 1971 as in 1978. Stock lift, duration, and overlap specs were enforced in both instances.
The piston in 1971 would have been required to have only the reliefs placed where they were needed for valve/piston clearance and they would have been no deeper than required for actual valve clearance. In 1978 the piston top would have been required to conform to the factory configuration. I don't have a '71 Rulebook and I don't know what horsepower ratings were established in either instance. The Corvette appears to me to have been a '66 while Jim's car was a '67 Fairlane, I believe. The Corvette (if it was a '66) would have been a 427 with a single Holley. Jim's car might have been either a single or dual quad motor. It seems to me that he ran it both ways at various times but most commonly with a single carburetor. |

Old stock vs new stock...........A cars minimum weight was the shipping weight back in the old days. No driver weight was accounted for. You were allowed 5 gals of gas and if you were light you could add a spare.
If you had a driver that was light, you had an edge. Pistons......rings could be moved up and you could run any rings. Forgedtrues were pretty popular...... Valve springs had to check at stock pressures and we usually killed them if a shift was missed. We ran GK and Lunati cams that had stock lift and duration.... 7" tires and they were checked for width. As they grew you had to cut them or use a cheese grater. M&H's were usually on stick cars and when Firestone came out with their "gumby" tires a lot of automatics used those......They were very soft and the hot rubbber from a new "trick" technique known as a stationary burnout.....burned the heck out of my ankles as I held the car.......

The first iteration of Kent's 302 was in that car and ran 11.19@121 in 1982. Kent bought it in 1985 and he did much better with it than I did.[/QUOTE]
Dwight I think the east coast air was a contibuting factor to your motor running better in my car. :-) Kent |

1971 would have been the last year for the 7 inch tire deal and aftermarket pistons, deep oil pans, etc. . The "NEW" stock eliminator began in 72. I think it was 74 or 75 brfore they were allowed headers again and real 9 inch slicks instead of those DOT slicks.

Giving credit to SE and Jim, one of the outstanding performances I remember was at the winter series race in Lake Charles ('85 or '86) where they ran 10.80s in D. I believe it was the red car. I was in B there and could only run a few hundredths quicker. We were all bad back then!! ![]() |

Dwight:
Just talked to Verne. I needed him(with his computer memory) to confirm my memory of of that race. We set the record at 11.27 and backed it up with an 11.31, in fact I have the record certificate to prove it. I remember that was a fun time to race because you had a bunch of guys in your class and all were friends and trying to out perform the other. Of all the things I miss about racing that is the thing I miss the most. Verne doesn't remember the 11.19 run but I wouldn't argue with you since most days now I can't remember what I had for lunch yesterday. You LOOONG time Buddy; S.E. |
