run those numbers on one of the on line HP calculators and see what you get.
I loved that stock 1970/1971 6 quart Hemi and six pack oil pan with the stock 6 pack 3/8 pick up up
I did find out that it would loose some oil pressure after a 134 MPH 1/4 mile run when I let off after the finish line if the I let the oil level get near the add mark, no problems with it near the full mark on the dips stick up I shifted it at 7000 RPM + or minus 300 RPM and it would cross the finish line at 7000 RPM shruggy
That motor ended up with 4.300 stroker crankshaft with 2.200 rod journals and BB Chevy type 6.800 long H beam rods, never had a problem with the oil foaming from to much oil in it, even with 7 quarts in it work
I made and used home made crank scraper for it from day one and modified it to fit the longer stroke after replacing the 4.250 stroke crank with the 4.300 stroke crank shruggy


That oil pressure loss does scare me a bit lol
