Panic, the GMC engines, especially the late military blocks like I have, have much more meat around the cam bearings. My idea was to offset bore the cam bearings to use 55mm cam bearing. These have an OD of 2.3" and by re-cutting the bores with this new diameter on the bottom edge of the old first cam bearing the cam will move up .150. This gives the same crank to cam center distance as a SBC (opens up many options). True, not much but I'm also destokeing with a 228 crank. With both in place and steel rods the cam should be plenty stiff, no notches, with a 55mm bearing size, allowing me to use some of the better grinds.
