Ken: I believe you are correct that you had the first small block auto in the 10's. I was there and watched your pass! I was then racing and still run a 340 car, so I watched everybody pretty close in mid 90's and never heard of another car going that fast at either a divisional or National event!! PS: I recall numerous articles and ads that stated Jim Waldo had first stocker in 10's although I didn't observe that run myself...........................By the way if it wasn't for Al and Ken Etters help we would have quit Stock Eliminator after the first few races.

Pretty sure it was Jim Waldo as well. Someone else will have to help with the date. Appears he's won a few times.

It Was some fuzz when Bobby D ran first in the 9's at mission that Waldo did his first in the 10's almost exactly 20 years before(i think) or something That is i guess under current(evolving) rules....what was different with the car Mark Y talk about and the rules back then?

1. Tires - 7" in 1971 v. 9" in 1978 2. Pistons - Unrestricted on weight and valve relief in 1971 v. factory piston in 1978 3. Allowable overbore - .060 in 1971 v. .030? in 1978 (things were changing pretty fast in '78. I'm not sure on the overbore rule at that point in time. What else am I forgetting? |

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. |
