True. The class that I'm researching is called pure stock muscle car drag racing. The pistons can be aftermarket as a 1.5 increase in the compression ratio is allowed. No headers and the ignition system has to be stock, a curve kit is allowed. Quality machine work and high tuning skills are important. Any gear ratio can be used. 2200 rpm stall converter is the most that is allowed. I'm thinking that it would be fun as you have to get the best performance from what the engine came with from the factory. Since the high performance 360's have the 340 cam and heads that it would be a good choice for a build. With the 340's having different compression ratios was the intake valve closing point changed or the LSA, overlap, etc?
