Old6 If you will go to tulsaracewaypark.com forums/nastalgia you will find SDRA's current rules. Begining with the 2010 season, 4bbl's will not be legal. This was done to control high dollar/high tech equipment, and to make the cars look more era correct. It also brings ingenuity back.
I think that if the Good Lord is with me, and I actually get to build one of these - it'll be SDRA rules. Mainly because you guys are closer, I might actually persuade some fellas closer to me to build some if the ball could just get rolling. We have a high number of outlawish tracks around, mostly 1/8th mile. I've had so much trouble with 3 speeds already behind a street Hudson - I just dont want anymore of that. Ironicly, my oil filled cork clutch is proving to be alot tougher than I ever imagined it could be.
There is alot to be said about ingenuity. Evidently all mine stops where the bellhousing bolts up. I'd sure like to see/hear about some of the mopar flathead builds out there? I'm a Hudnut, but keep a deep soft spot for those mopar workhorses.
