Im rebuilding a 1965 Chevy 230 cid Block into a 250 cid Marine engine. But I notice differant part numbers for 230cid & 250cid cam bearings?
In Chevy Truck blocks the CamShaft is the same in ether 230 or 250. Im using a Marine 250 cid Camshaft.
Is there a differance in the Inside Dia. on the Blocks? Or is there a differance in the Outside Dia. on the Bearings? I would like to understand? What is the differance? So I can order the right New Cam Bearings that will work with the 230 cid block & 250 cid Marine Camshaft.
