Class mill rules. OEM cast iron block No angle plug, vortec, or after market heads. Stock only. Rogchester 2 barrel. OEM intake. Headers permitted. Stock rockers, and value springs. Solid Lift or hydraulic cams. No rollers permitted OEM HEI distributor with stock coil. (Prolly wont after tech cause no runs them after tech anyway) Was thinking about building a 327. Double hump Heads and Rochester intake from cast heads with their magic work done to them. Jet 500 CFM carb. Light weight billet crank. Reduce drag where ever I can. And most likely a 097 came. What else can you think I need to do?
