Thanks for the input guys ! After further research (found my shelby data sheet) I see where the block is set-up for either 427 or 351c bearings. On the clevite site, their catalog doesn't show the CB 756 as a FE rod bearing. I scanned the entire listing and did not find the CB 756 anywhere! They are in my H beam rods of unknown manufacturer, and they seem to be ok, I'm just curious as to what their original application was. Also on the clevite site is a statement that some "P" bearings are "hi performance" , but no details as to which ones. Also referenced are the "h" series "hi perf", so I'm trying to find out if those are available for my application.
