not sure what you're referring to as a "compression ratio tool". There isn't any device (that I know of) that would take into consideration all of the variables (cam lift, durration, etc) that would allow a plug and play type setup..
please explain..
compression tool? i never said that. i know there is a formula for figuring out your CR. i just dont know the formula. it is a combination of bore, stroke, gasket bore, clearance volume gasket volume, head volume, piston top land diameter,crank throw, cylinder volume etc. can think of the rest off the top off my head. but there is a mathematical formula to give you exact CR. that is what i am asking
