math shows me I'm ....
Your HP computed from your vehicle ET is 462.09 rear wheel HP and 513.43 flywheel HP.
Your HP computed from your vehicle MPH is 442.55 rear wheel HP and 491.72 flywheel HP.
So, it's just a guess...

570 fwhp at 7100, 492 ft lbs at 5600
460 rwhp at same, 410 ft lbs at same.
Doug, what formula you using ? Ive seen where the estimated rw and fwhp are very close like you guessed, but in tbe real world, i think the old school drive trains we use are hp hogs ! Thats why i use a 2004r and an 8.5 10 bolt. A th400 sucks the life out of an engine, but it will live , lol.

Looking at his build, I'm guessing it's close....Hope I'm wrong, but a dyno will tell.....as well as the track
You have an old school Moroso slide rule ?

I just rattle some nonsense off the top of my head thinking back too the thousands of threads ive studied and magazine builds ive read about, along with the always disappointing dyno runs ive done on my own junkers with stalled autos. They are always ego crushingly low compared to what my air dyno thinks they make at the flywheel. Like my 540 hp 406 ( with the parts it should be that easily ) that only made 356 rwhp, but according to the et/mph to rwhp predictors should have 450ish wheel . I also learned that just because the chassis dyno crushed your internet hero hopes doesnt mean it wont haul a$$ , lol.

Your HP computed from your vehicle ET is 522.73 rear wheel HP and 580.82 flywheel HP.(guessing the weight was 3600# )
So you can see it's close, but I guessed at the weight which is on me.
