So,if GTX John can run 10 seconds with a 318 in a 3400 pound station wagon, what are you big cube guys doing wrong? Given an unlimited valve train, intake manifold, and exhaust he is still running stock compression and cast iron heads.
We aren't in the racers forum are we?
Did John street drive that car?
What we aren't doing wrong or are is not having 5.xx gears and 5000 stall in a race car, no matter what the weight. This is where I try and clear things up by 'in general' saying... stay in your lane.
