HI NEW TO THE SCENE HERE. I BELIVE THAT THE SCAT CRANKS HAVE BEEN USING CHEVY CONNECTING RODS BECAUSE THEY AR THINNER ON THE ROTATING PART OR THE ASSEMBALY.BUT LIKE DAVE SEVERSON MENTIONED IF YOU BUY THE WHOLE STOKER KIT TOGETHER YOU KNOW YOU HAVE THE RIGHT COMBO. THE MACHINE SHOP WILL BE ABLE TO HELP IF THERE IS ANY CLEARANCE ISSUES WITHE THE ROTATING.
