i would say some where in the 325 hp range .....you wont blow up your engine on a dyno with your mods...dyno tuning with your mods will add lil bit more power more its more to make sure your engine has very good air fuel ratio so ur not running lean or rich and adj the timming and so on...

320 to 350 at the flywheel. With the mods you have a dyno tune would make your stang more powerfull and streetable but it isnt necessary.

The car should make around 300 to the wheels and run 12's with ease. Be carefull with all that power at such a young age.

thanks alot for the responses guys, well i wont have to worry bout driving it for a while becuz i live in new york and theres snow on the ground already so im not going anywhere. Becuz its going to be off the road anyway i plan on puttin a vortech in it but only puttin out bout 6 or 7 lbs, is a dyno tune a must after the sc? i have to sell a 92 gt to get the money for it, i know its the wrong forum but if anyone interested in it let me know...new motor with 13k miles on it body is shot ....great winter project.

Why are you so afraid of the dyno? If you put on a new S/C, of course you are gonna need to dyno it. Also, you may want find out exactly just what's inside of that block of yours. I hope it's not running flat top pistons. Sounds like whoever built that motor was going N/A not S/C.
