compression ratio prob.
im trying to figure out my compression ratio. i use dyno2000 but i dont believe the results i got were accurate. the specs i put in were 4.166 for the gasket bore size, .040 for the gasket thickness, the pistons have 4 valve reliefs on them that i've been told are worth about 4cc's, the chamber size is 72cc's. the deck has been milled to be equal with the top of the piston. is there anything else i need to know as far as calcuating the compression ratio?? dyno2000 said i had somewhere around 12.3 CR. im trying to find the easiest way possbile to calculate it. thanks for the help, i appreciate it.
