I'm in the middle of building a 383 and I ran into a big problem. I turned the engine over after putting in all the mains and rods, rolled sweet to. the I put the cam and timming chain on. went to roll it over again and the the rods are hitting the cam lobe. can anymore help me with this. I'm running a CC306 with a SCATT crank and don't know what I need to do to make this work I allready had the bottom balanced and clearanced.

thanks
