How much horsepower does this have

Just curious how much compression that has and what rpm he’s shifting at. No doubt there’s some serious mid range torque and big average hp numbers past 5000 rpm going on here with the “methanol magic”. Is that the advertised stall speed or is that what the converter is actually flashing at?

Shifting at 6700-6800rpm and I will never mention advertised stall. He semi babies this car because the rearend has zero upgrades other than the usual spool and axles. If he gets the car out in 2022 it will have a new powerglide and hopefully a converter in the same area or a touch higher.
