Don't even bother then, just move the springs inboard and mini tub it with CalTracs. All that work for a ladder bar is a waste of time and money. If you want traction back half it with a four link and be done with it.
I second this. This setup is good for 750 h.p with 10.5" slicks,so minitubbing it will just make more room for even bigger tires.Mopar muscles project car the B3 bomber is a 67 Barracuda with a 750 h.p big block and it uses this setup to run low 10's on used wore out 10.5 slicks.
