The late Mike Ulrey once said that he preferred racing top oilers. He raced CJ's in the 70's and was very sucessful. He dragged raced them and didn't think the side oiler was as strong. I disagree with him there b/c they are basically the same block with the exception of the side
oil galleries. MY point is he beat the crap out of the topoilers won major races and did well. The side oiler is definately not stronger and I doubt any even a KC supermotor will tach to 9000RPM for longer than 2 minutes without blowing up
