Scat Crank Repair

:Di had the same prob and a welded crank from someone who knows what there doing will work fine, never had trouble with mine till I put a dynamic convertor in it, sent it back and checked it they said it was fine , go figure, guess what it eat another crank so goodbye convertor, I switched the convertor to a ptc and shortened the drive4shaft a little and no more probs, everything worked brfore the convertor, the driveshaft was a little long so I guess not enough clearance on that and the convertor combo was a killer hope this helps
