My 318 Build with questions

prostreeter9 said

Hey guys:

Maybe some one can tell me the best way to figure out what my compression ration will be? I still have the heads off and plan on resealing the lower end before putting it back together. I would like to be in the 9:1 range. With hope that the combo gets in the 300 HP range.

Here ya go: How to Check Compression

This is your best bet if you want to know what your actual static compression ratio is. Dynamic compression ratio is also important but you'll need to figure static first. It is hard to give a good answer to your question without being able to measure the parts you have, so you need to do it yourself for the most accurate results.
