Expensive is definately the word... I am now actually looking at going to Turn Key engine Supply's crate with cam and ECM upgrade.

I can get all accessories. ECM, starter and fly wheel. I just hope the stock pan on the LS7 will clear. Different is definately more expensive. Thanks for the advise for ATS looks like they will work.
I really wanted to do a 700hp motor, but I hope 630hp will get me into the high 10's and just plain haul butt. Thanks for all the advice. If anyone else has somemore feedback or suggestions, please advise.... Thanks Guys
Blessings
