Just remember anything you do that makes it vary from stock, you're gonna need a custom tune to compensate for it. Before choosing your parts combo talk to some tuners to see what they think. I haven't dealt with any of these guys yet but will surely be talking to some when I get my HD project going since I'm using a '96 Vortec 7.4 in it and will be emissions-exempt, so the very first thing I plan to do is give it a custom tune. Try Wester's Garage, PCMforless, wait4me, there's a bunch others, can't say if one place is better than another, time to start ringing some phones.
Do not ignore this step or you will hate life...
