Awesome, thanks. I have lots of seat time with 4.6s, but this is my first 5.0 I will be racing

Bounce the tach off the dash a couple times and then dump it!
... ok seriously escogt is right on target. The factory motor doesn't make much power above 5,500 and with factory valve springs you don't want to push it or you'll float the valves.

Update - 2023 - Looking to buy 81 Mustang, 82/85/86 Mustang GT, and 79 - 86 Capri (No Sunroof). Not looking for all original/show cars or convertibles - I will be modifying. Would be nice if both were - Black Interior, PW, PL, AC, No - or very little rust. Motor/Trans/Axle not important. Options negotiable with price.
5500 even sounds a bit high for an '86. The '86 GT had unique "high swirl" heads which limited its top end performance. Back when I used to do a lot of open track driving, I spun mine out to the rev limiter (6250 RPMs) a few times. It survived, but it sure didn't make power up there.

Ok thanks, I can feel the power go sorta flat past 4,500 rpms. I gotta get it to my buddy's dyno and make a few runs. Just to see real numbers.

4,500 is peak torque on the factory motor. Falls off after that.

The stock 86 GT I drove for a while ran best when shifted in the 4800-5000 range.
52-5300rpm will net the best ET's with the stock HO camshaft and 86 top end.
