[84STANG GT]

I have an 84 Mustang GT and it has a 90 model motor in it that has been converted over to carb (650 holley) 85 ignition, factory tube exhaust manifolds, aluminum intake, and a msd coil, the guy I bought it from said it has an e303 cam,h pipe w/ no cats.3.55 gears(8.8)
I have driven mustangs before and I know that this motor with efi and smog stuff on it was rated at 225hp and 300ft. lbs.
This car comes alive alot when you barely step on it. not like any of the 5.0 efi cars that I have worked on in the past (all stock) maybe a fipk or something.
oh it does have under drive pulleys and a manual rack so no p/s.
please tell me what you guys think I am pushing.
Would this car handle a 50-75 shot of NOS without immediately imploding?

i don't know how much power your pushing but it can handle a 75 shot if your motor is in good shape.

My guess would be 275 HP at the flywheel. The lower rear gear is what probably makes the difference. I'd stay conservative on the nitrous with a stock bottom end 75 shot max. Also who wants blown head gaskets.---Chuck

Im not sure what amount of power, but, the e303 cam is what Ford Racing puts in there 5.0 Crate Engines. Those make 345 HP, but they have GT 40 x heads, which make a huge difference.
