70,482 mile 1999 explorer motor. F-cam, rpm carb intake, 750 carb, mac headers and billet dist. Any Ideas? I've never ran gt-40p heads before or an f-cam. Thanks Troy

Random guess of 285. I had a very similar setup.

The carb is too big, but if you know how to tune you should be at least 260 to the wheels. I don't know about 285, i think you'd have to run a higher lift cam and mill the heads to bump compression.

I wish I had a 650, the 750 is all I have to work with right now.

I think they are both near the ballpark. I would have guess 260-265hp around 300ft/pounds of torque with a 5 speed. Less with an Aod.

Id say thats a real good guess form what I have seen from others

I'll go 260/300. Thats pretty close to my old combo.

Is that carb mechanical or vacuum secondaries? Shorty's or long tubes?
