Denis4x4, Interesting info on your engine. One of mine is similar.
FWIW: My '31 S?W Town Sedan with T-5 transmission.
My full pressure "B" engine block has: Inserts, high output Stipe oil pump (28 psi warm at 2200 rpm, 20 psi warm at fast idle), counter weighted crank with SBC rear oil seal (no drips yet @ 20k+ miles), 7.3:1 Lion Speed Head III milled .074" and relieved at the intake valve area, FSI Ignition, cast iron header (Tried tube header but no change in HP), Single Stromberg 97, Sterling Rattler flywheel with V-8 Clutch, front damper pulley.
77 HP a with 24 degrees advance at 2900 rpm. I would say almost the same as your engines output. I ran the engine up to 2900 rpm on the engine dyno (water brake) but when on the road, I shift at or near 2600 rpm. I do not recall what the HP was at 2600 rpm.
Good Day.
