Or anyone that knows. I cant find (get) a part number for clevite main bearings for a 4g64 crank, ie building a stroker kit. Or any other options other than stock, oem bearings. I have heard all different stories from a one off type bearing from another car to machining one to fit. I have called a few spots and it seems like its some kind of secret of something. Any help would be much appreciated and thanks in advance

 

did ya give AMS a call, I am sure they will help ya
