what engine are you starting with? year? are you starting with an EFI 302? Manual or auto? Gears? Tires size? etc.

Most basic thing would be a head swap to GT40 or (better yet) aftermarket heads. Don't be afraid to go for big heads, 190CC+.

Speed Density Mods. Headers, Dual Exhaust (or something free flowing) Heads, 1.7 Rocker Arms, a mild cam ( speed density friendly cam) you really need to call the cam Cos. on this one. You'll need an efficient intake system and exhaust to support the cam. Or just blow it, Blowers work great on speed density setups & so does nitrous.
