383 Stroker Build

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.

I hag this problem awhile back and I was told to go to after market rods with cap screws. and it worked for me.. just my 2cents good luck. also a small base circle cam my be the answer..

CONFIRM CAM / CRANK TIMING . dOES THE CAM SPEC FOR AN ADVANCED OR RETARED POSITION.
