boost vs. N/A
Im about to take my 94 z28 off the road to do a motor build and start making some good numbers. Im stuck inbetween building a low compression motor for a S/c or a turbo. other option is a high compression 383 head and cam motor. Anybody have good advice/opinions on this subject that can help me decide???

Depends on what you're looking for. A supercharger build will run you 2x the cost of a high compression 383, but with LOTS more power potential. What are you looking to do with the car? Any specific numbers?

I was using the static ratio as a rule of thumb, dynamic compression can also be altered with the cam, but a higher static ratio, (usually) means higher dynamic. So I would attempt to stay under 12:1 if I were planning on running pump gas.

FWIW, I'm running close to 13:1 with a moderately-sized stroker cam and have a DCR of around 9.5:1. Runs perfectly on 93-octane.
