Thanks Rich, not sure when I am going to change the diff. No rush right now but it should really move with some higher gearing. I am currently considering a few options for the rear diff, including a ford 9 inch.
The S50B32 is nice motor but considering what you end up paying by the time you add the 6spd you might as well pick up an ls/t56 dropout. Its a bit more money for the install but you cant beat the power. I suppose the alternative to the LS swap for me would have been the Fox body Ford 5.0 motor. You don't even need custom headers, and can build/FI it on the cheap.
