Sorry about the post I am brand new. Lets start again. Nitrous with gas will burn straight across the piston. Methanol and CH3No2 that is nitromethane will burn straight across the piston. The piston needs to be pushed down the cylinder straight not like the gas fired motor that pinpoints the piston.

1940 Chevy 1 1/2 ton, 1959 Chevy 1/2 ton, 1966 Chevy C20.

I can explain it to you but I can't help you understand it.
