408 Stroker

also at what altitude was this dyno run, and confirm if this is crank HP

I see in one of your postings your previous setup made 520 HP and 560 FT/LBS with 10.4 CR, the Air Gap and a 242/[email protected]”/.603” lift 106LSA cam. What where the changes you made afterwards? Looks like you barely gained any meaningful horsepower but lost a good chunk of torque.
only changes were victor and 13cc pistons replacing the 23cc dish pistons cam is as you posted. **** it going in the scrap pile on with the next project
cyl pressure is 185
