BHB4408
Novice racer, building my own 440 with 512 stroker kit. Trickflow 270 Heads with flat-top ICON pistons at a 12.1 ratio.
I degreed my cam. I did it multiple times, exactly like the cam spec's told me to, and exactly like multiple internet searches told me to, and it had me Advance to the #2 position on the lower timing chain sprocket, to get the 104 as suggested by Bullet Cams. Any other setting on the sprocket didn't come close. The head-gaskets I ordered will give me .040 piston to head clearance. With gaskets in and heads on, I'm using the clay method of checking Piston to Valve clearance, and I was expecting to find about .010 on the clay. But doing the test over and over on different cylinders, I'm getting about .22 (about a quarter inch of PTV clearance) on both intake and exhaust valves. Does that mean I've degreed the cam wrong, or is .22 something that I should be happy about?
Thanks for taking the time to help me out,
