I put a 13hp predator with the hemi head. Stock belt. Unfortunately I have to weld extra brackets to attach the grill back and extend the hood support rod.. huge motor.. but what I’m using it for I need.
What engine do you use to replace the originals. Will the original sears pulleys work for the drive belt and the mower belts. I hv an 68 SS 12 with manual transaxle. Thanks
