Machine shop has had my stuff since June 5. Not sure when I'll get to assemble my permanent engine. I have the Crown Vic engine in reserve.

It's not going to make that much difference. You'd likely have to dyno it too tell what difference it makes on the torque. If the F4TE cam is usable, then by all means, use it. Mileage will be a little better for a daily driver than the HO.

Compared to what you are starting with.. an '86 truck motor, a rebuild with the ZE cam will make more power everywhere.

You told me long ago that I may be able to use such a cam with flat top, no valve relief pistons if the E6SE heads are used. (I have also recently read your sort of glowing review of the E6's benefits from back in '06) I need to mock up the heads with the cam and check that out. Also check to see if the E5 valves clear with the stock cam.

The E5s with valves at full lift.

The 86 HO motor's output was something like 225 hp I think. That's with the E6SE heads and the HO cam. 86 was a one year deal for that combo for the HO motor.

Would that 225 be with this exhaust system? I pulled it because I plan to replace it with something more free flowing. Looks like to do that, I must run no 🐈s.

Mustangs those years had dual exhaust. Might be wrong on those HP numbers, might be around 200HP.

Doesn't matter too much. Those readings happen in a rpm range that'll seldom be used. And I recall your views on the E6SE heads too. In the'86 Mustang. If not for you and Ski I would have dismissed the E6's out of hand.

Maybe driving the truck for over thirty years with stock cam and E5 heads is why I never exceed 3000 RPM. The truck trained me.

Yes 200hp, and the same motor with E7 heads made 225hp which is a great indication of the differences in the heads. Also note that peak HP number is still only 4500rpm, the Mustangs were smothered in factory trim just as much as other vehicles of that vintage.

YES!!!! You won't friggen believe how much better the motor pulls with a cam that actually allows it to breath.
I said earlier that this cam will produce more power everywhere compared to the stock cam. You're probably not going to believe this but here it is anyway... with this cam and a free flowing exhaust your otherwise all original motor should make in the neighborhood of 100hp more than stock. The spec in '86 for this motor is 150hp and 270tq and that was all due to the tiny factory cam and cork like exhaust. If you successfully address both these issues it will make 250-260hp with 325-350tq no problem at all.
