I'm having an interference problem with a 383 stroker build. I have clearanced the crank so that it clears the block When I install the cam the connecting rod caps hit the cam lobes. It only hits on the #2 and #6 rod caps. This is a 350 block with Scat stroker crank, stock connecting rods and crane cam. Any ideas on this? This is my first 383 stroker build.
