Pressure seems okay when warming up but drops when it is fully warmed up. I can't hear any knocking, no metal in the oil, and the oil pressure gauge is good. My problem is when I bought the motor the guy said it was a 350 with maybe 9k miles (said it was a crate motor, but I'm not so sure now). I finally looked up the numbers on the block and it turns out to be a 305. I really don't care about that part but I put a beefier cam in it (thinking it was a 350) and am wondering if I have too much lift for stock 305 valves, rocker arms, push rods etc. Any ideas? I'm going to cut open the oil filter tomorrow and see what's inside.
I put a Mellings cam with the following specs:
Cam Lift
INT. .298
EXH. .298
Valve lift
INT.447
EXH. .447
Lobe CTR
INT. 110
