I know you can't go too much over stock. As long as you stay under 220 duration and 112 LSA or higher you should be ok. If you pick a dual pattern camshaft keep the split small. I would use something like this. Crane Hydraulic Flat Tappet Camshafts 113931 - SummitRacing.com or Isky Hydraulic Flat Tappet Camshafts 201262-27012 - SummitRacing.com

Some TBI/cam info: TBI CHIPS TRUCK MODS

Unless cost is a factor, rechipping the ECM is no biggie.
