I'd be interested in what the stock shaft is like? How big? Was it a V6 truck before?

4.8L with cam, probably isn't going to pretzel the stock shaft.

I'm leaning towards, if it's not broke don't fix it.

However, I had ActionMachine.com make my 56.75 long 3.5" diameter aluminum driveshaft for my 6.0 4L80 swapped 68 shortbed. 1350 front and rear and it's a work of art. Forged Chromoly yoke's on both end. It's probably massive overkill...
