I'm Awesome
Its the stock drive shaft with new u joints/bolts... its a SS so, I am pretty sure the drive shaft is bigger anyway due to the big block and 14 bolt rear. I have had mine on the dyno with no driveshaft issues.Are you running the truck's original driveshaft or have you made a new one? I ask , because I'll be planning some dyno pulls in the near future, after my LS swap, and am concerned about the critical speed of the stock shaft. Thanks
