What do you think about this 318 guys.

I saved you the math in post 12. He finally admitted to that number.
oh sorry... i am bad about reading back... and yeah.. saying it's a 318 doesn't make sense.. other than saying 318 block...

On the upside.. this makes me feel better bout doing a 390 if i don't run into a cheap 360 block... i only want 450ish hp anyway.. just dependable.
