about 175, take off the intake, make it a 4 bbl, and buy aftermarkey heads! Those were early emissions years. It is very easy to convert that engine to about 450 hp though, you don't even have to mess with the bottom end to do it. Just take off all the emmissions crap., buy headers, and midpipes with no catalytic converters, and once it is a 4bbl, your possibilities are endless. You can even buy dual quads for that engine.
