When at Westec working with Steve,he has a formula he uses for street engines he has arrived at over years and hundreds of engines of all brands.Moderate hipo street engines withcams in the 230-240 range and running on 91 pump gas his dart goes to 1.25 HP per CI.For cams in the 250-260 range he moves up to 1.5 HP per CI.Not gosple but will get you in the hunt.Did not talk about full race engines.FWIW,Tom
