Good to know. The engine builder i've got lined up builds 2000HP Chevy engines, but has a lot ov experience with racing a Mopar 383 back in the day. He has a dyno and said it'd run around $500 extra to dial it in and give me some numbers, try a couple things, etc. Sounds like a deal. Personally, i was leaning towards doing that, but after reading this thread i think i'll hold off on the build till i've got that extra 5 bills.
