It's hard to estimate the horsepower for a random car...but for an average alum. heads, mild cam and aftermarket manifold set up...I'd imagine somewhere around 40-50 "real" horsepower that you can DEFINITELY feel. Without any port work or anything a decent heads/cam/intake combo should put you somewhere around the 300-320hp range...providing that you have all of the necessary bolt ons, exhaust, etc. If you're thinking of going with some heads...AFRs have my vote!
