trying to figure out how the 3.73 gears factor into the hp at the crank. God I love newbs.
"precision ground micro polished crankshaft" That has to add 100 hp alone.
And stickers, don't forget to add 10hp for each Summit Racing sticker.

Friend with an E-Brock headed, E-303 and E-Brock performer intake makes 290hp at the wheels through a T5. Rest of the engine is stock 5.0.
He's running 1-5/8 shortie headers and full 2.5" exhaust. Pretty sure he's running 75MAM, 70TB, 24lbs injectors, 255lph pump.

That seems awful high (360+fwhp) IMO.
OP, I don't think you've cracked 300fw personally

With my stage 3 ported, cobra upper/lower, p-heads with an e-cam in my sig, ....you should be in the same ball park. Mine was tuned by racer Brand Brand at Atlanta Chassis Dyno, it's accurate as mofo. Dyno sheet is in sticky dyno-1/4 time slips.
Need more info on your car to give a more educated guess but if the car is mostly stock(other than the engine) anywhere from low 13's to mid 14's. If it's a drag car ie slicks,race trans,removed weight,etc you could sneak into the 12's
