The oil seal journal on the rear of the crankshaft has directional knurling. I think the front seal has a directional pattern molded in. The new cam would require a reverse rotation distributor drive gear (and driven gear) which would turn the distributor and oil pump in the 'normal' direction. This would allow the thrust on the distributor drive to hold the camshaft in the block. Reverse rotation SBC are common enough that an engine builder should know what to do. Is the SBC cam gear the same as the inline AMC six? If a cam grinder can't cut the reverse rotation gear on an AMC cam a gear drive would reverse the rotation of the cam.
