I have had two costom cams specced out by Geoff Skinner at Engine Power Systems, he has proprietary grinds and lobes on some of his setups A ton of guys run his cams, I have NEVER heard a complaint. Give him a call, 225-751-8500 Awesome guy to deal with, You wont regret it. If you are wanting great power as far as intakes, You will need a F.A.S.T intake setup. I have a ported 92 and his cam in my 383 in my sig.

RARON455, I'm considering a 383 build myself. I know when you go for power you sacrifice fuel mileage, but I'm curious how much. With your setup, what mileage do you see on average? Highway and city if you've observed both, and what did you get prior to your build? Thanks!
