The roadsports series that I participate in allows only limited tuning from factory standard, to keep costs down for all involved, and to stop those with the biggest wallets from automatically winning every race.

Engine uses the required standard Pontiac 400 block and heads and Rochester carb, but with suitably heavy secondary jets. Cam is free, so i'm running a Ram Air 4 with appropriate lifters and racing timing gear and chain. Forged pistons are a must, given the constant hammering the engine undertakes. Electric fuel pump is fitted and sits next to the battery in the boot.

Transmission is via the standard '78 Borg Warner T10, although as luck would have it, the car came fitted with the close ratio version - ideal for track racing. Im running a 3:42 diff ratio, which will give a top speed of 153mph if the engine is revved up to 6,000rpm - although i generally dont take the motor past 5,000rpm at the moment. Fastest ive managed on a track so far is just over 130mph coming out of folly at Castle Coombe.

Much much more information will be appearing here soon. Be sure to check back!
