So I want to build a bid block chevy in a couple of months tho will be a racing motor. I need to learn a few things before I even start this project though. I would like to know if you guys could give me advice on building one. I know what it takes to build an engine just not the technical stuff, such as what determines the compression of your engine or even how I decide what fuel to use. If you guys can give me advice I would be most grateful
