Well depends who builds it, elevation, dyno, but mid to upper 180's on good gas would be in the ball park. KWS and Lee's and Carpenters advertize higher numbers. But speaking from years of experiance and endless mods the claims never come true. Cam timing and bigger tb's will make more but ya gotta make a decesion on what kinda of powerband ya want. We played around with several combos, some made 3-4 hp more but the low and mid was terrible. Personally, do the cams, and add small dry shot and you will make as much. Only downfall is he bottle refill and keeping the right pressure. As long as you don't get greedu with the jet size 40-50 hp ypo should be okay.
