I put a efi engine from a 1990 stang in my 68 and am curious what kind of power I can expect with my mods. The crank rods and pistons (forged) are stock or replacement, bored 30 over. E303 cam, professional products intake, 70 mm tb, c&l maf and elbow, 24 lb injectors, 1.7 roller rockers, underdrive pulleys, k&n filter, msd coil, FMS Y aluminum heads, long tube coated headers. Thanks for the help, I am thinking somewhere around 330-360 but have no idea.

One last thing, do you think I should throw nos in the equation for that additional fun factor one in a while? I was looking at a Zex wet system.

to the wheels youre likely in the 250-270 range depending on the tune of the car.Y heads are OK but not a great power head but when combined with a nice mild cam like the E and your intake upgrade you should have a nicestreet car on your hands...flywheel HP likely around 300 so a nice jump over stock rating of 225...remember these cars stock usually dyno in the 180-190 range on the 5spd cars.

Crank or whp? Id say your figure is pretty close. Enough to smoke stock non S/C cobra's.

I was thinking power on the crank.

As stated you should be around the 300 mark..and surpass that if you had the car professionally tuned..I could see 320 flywheel. The overbore accounts for no gain..it's a standard cleanup for the cylinders. Having the heads ported and or upgrading to a stronger cam would obviously provide you will more power. Generally the aftermarket mafs tend to fatten up the fuel curve a touch with the ford ECUs so you would find a few ponies with the tune added.
