Custom ground camshaft, low power

moper said

Can you list the rest of the engine specs? Who ground the cam? Was it degreed? What kind of power numbers are we talking about?
Larger duration vs actual lift is not a big deal, but other factors amy make any cam not work as intended. If the engine in a place where you can get some cylinder pressure readings? (is it in your car?)

Engine is a 77 440 block bored .040 over. forged crank out of a 70 440 with journals turned down to clean up a spun bearing. kb237 flat top pistons with valve reliefs. What other specs do you need? I local machine shop (Edge bros) sent off to have it ground. Not sure who ground it though. I payed for it to be degreed when I had my long block assembled so It should have been done. I'm making 310 Hp at the wheels in my duster at 5500 rpm. (365ish at crank im guessing?) I'll have to look up the TQ numbers. Cant remember off the top of my head but I believe they were lower than HP. I can get pressure reading from 6 of the cylinders. #4 and #6 aren't worth the hassle. I can hardly put the spark plug boot on.
