Ok, it's amazing how much i've learned already in just the last day from this post. All your describtions have made sense(some more than others ) I haven't spent a dime yet. I got this motor from a buddy who is leaving town and had parts to give. Got a 350 block, heads, intake and that cam.....but knowing what i have now cam wise really helps in deciding which route i wanna go in the build. I'm definatly gonna get those books and read up on whatever I can. I know an engine builder....he built my 400 chevy in my Jeep, plan on picking his brain and parts bin. Once again thanks soooooo much.
