Steve,
Thanks. I have been wondering about that myself.
Admittedly my engine knowledge is limited and I am not very good with mechanical things.

I often wondered, how does one builder take a block and put in similarly ported heads and a a crank. With given pistons and cams from a limited number of suppliers builds an engine that puts out 715 HP, and builder B takes the same components , all he can claim is 500 HP from the same combination of parts?


This is assuming similar compression and similar parts.
Is one not telling the truth, or is there that much of a variation in the skills of the builder. What magic dust is being sprinkled?
Can it be the gas?
