1500hp from a stock block. Although that GT will have the 32v heads like yours.
Mines using the 3v head. Still allot of power can be achieved with bolt on parts.
Just bought a Roush charger kit for mine out of the states for under $1k. Thats gonna go near 500hp without going near a rolling road

Stiegmeier' "Snakebite" charger that could go near 1000hp with a forged bottom end and some trick bits.
That's all just weekend warrior stuff!
What power are you looking for out of that Stang unit?
looking for 1000hp at the wheels, not sure what its going in yet, might go mid engine 2wd using the GT gearbox, or else it will go 4wd using a modded dodge viper gearbox, 1000hp is about the limit for supercharger, above that u need twin turbo
here is a video to show how tunable the ford GT is, just a twin turbo setup in place of the supercharger and a remap, 1012hp at the wheels
