engine size autocross

I would 99% of the time take the cubic inches. So many people are into the destroke idea but RPM capability has a lot to do with valvetrain stability more than bottom end. Look at LS engines for comparison. 6.2-7.0 liter LS engines make better power than 4.8-5.3 engines but the architecture is nearly the same.

Don’t feel like you have to go LS. Traditional V8’s can work very well and, IMO, it’s nicer buying things like radiator hoses and other parts that were originally designed for your car and bolt in. Do what feels right for yourself. Big Blocks are awesome just as LS engines are.
