Tunnel ram 440

Ya I read somewhere that it was mainly to check that the cam was ground and had the key placed in the right spot on the camshaft, I think I am goin to go with comp cams I seen another guy run it straight up dot to dot in his 440 truck and it seemed to be right on the spot too. That time was with the 451 duster right?

Yes it was, that was its 1st. cam, the 2nd. one i went solid, had comp custom grind me one from there 520/540 core.
