I absolutely guarantee you that your engine doesn’t have a clue it’s a race engine.
Bet all you have and a lot of what you don’t have that 37 degrees of timing at peak torque is EASILY killing 20-30 HP. If it was 35-40 I wouldn’t be surprised.
Of course, that assumes you actually have 37 at peak torque. You probably have less than that and unless you set the timing at max RPM you don’t have 37 there either.
