Not as much as you'd like! Unload the intake and put a decent aluminum job on it-same goes for the exhaust manifolds, get headers. You are probably around 360 or so, not much more...........djs

more compression would help.
i can't see a problem with this engine going 13.0 in a b body.
with more compression and a new intake, probably looking at 12.5-8

Default I know where your going!

Not ever wants headers and big high rise intakes..

Sounds like a great combo there. They may tell ya to add this and that, but to look stock It cant be done. You have a good combo there. What tranny/converter and rear gear are you running? I would sat close to 400 Horses there and 500 lb/ft of torque. Your cam & X pipe will make more power than the stock engines. I have read that blocking the heat cross over during factory dyno testing back in the day would result in 20-30 horses more. If there was good bowl work it will help too. You would have know problem pulling away from the same factory car and geared package.
