I dont think you guys know what you are talking about. Yes the old strokers did have a problem because people use to offset gring there original cranks and use chev rods. The kits they have today are very good. You wanna look at the guys that use them. Everyone is going stoker clevos now. Standard stroke clevo is a thing of the past. Live now get with the real world and think before you start saying s**t that you dont know nothing about. There has never been a problem with 393 stroker clevos.
