Deuce4dad - I was kinda thinking that a 400 hp build may not be what I need - i'm reusing the stock 4 speed trans and rearend, and figure they may not last long with that kind of power, plus, I'm not sure how streetable that engine would be. Thanks for the explanation about flat tappet cam. Is the problem with the flat tappet that if it's not broken in correctly, the cam will shed metal particles into the engine? What is the correct way to break in a 350 sbc? I've never had a new motor!

prpmmp - i'm going back and forth on the motor. I don't want a junkyard motor, since I might be driving this motor for 5+ years, which is originally why I was looking at the $800 rebuild or the $1450 jegs or summit motor - just keep it stock and drive it for awhile. I may still go that route, but really like the info and ideas I'm getting on this forum.

rspears - I really like your idea of asking the local rebuilder about a custom 350 Gen 1 SBC with a roller cam. I'll definitely contact them about this.
