part 1 This video below explains the differences between the various connecting rods west bend,Chryseler and U.S. motor power offered over the years.

Using the older rods or stock factory bolts in high rev engines will result in total destruction of the motor

part 3 this video explains the basics for removing the outer cap edges of west bend rod bearings. a thrust washer must be fitted in it's place as explained in previous videa.removing the cap edges reduces friction ,allows better lubrication of bearing and allows higher revs. it also removes a potentially fatal flaw in the engines design.
