CAM BEARINGS

MANY MODEL A FORD BLOCKS ARE WORN OUT IN THE CAM BORES. THE ORIGINAL CAM BORE SIZE IS 1.5625". WITH THE ORIGINAL CAM JOURNAL SIZE OF 1.560" THIS RESULTED IN .0025" CLEARANCE BETWEEN THE CAM JOURNALS & BLOCK. WE HAVE FOUND THAT .006" CLEARANCE IS THE MAXIMUM RUNABLE WITHOUT PRODUCING A KNOCK IN THE ENGINE. IF YOUR BLOCK IS WORN TOO LARGE, WE BORE THE BLOCK OUT TO ACCEPT OUR MODERN CAM BEARINGS. THIS RESULTS IN THE ORIGINAL 1.562" BORE SIZE & A TRUE BABBIT BEARING SURFACE FOR THE CAMSHAFT TO RIDE IN. THIS GIVES ACCURATE CAM TIMING, VALVE SETTING & QUIET OPERATION.
