There are some "TBI" cams and " Computer " cams available. but the dururations are what are special. however they will still need a chip program, and there still very mild...

a good example of what happens if you use the wrong... friend of mine in my high school autoshop class, swapped in a newly re ringed/ bearingd Vortech 350 into a '95 K1500 short bed step side.. He put on the TBI heads to avoid getting a new intake, and even tho I warned him about the cam choice. he put in a " Performance 3000 " camshaft.. it's a camshaft that Napa marks as OEM compatible for many carb'd 350 powered vehicles, I don't remember the dururation but it's 112" LSA I think. .442" lift IIRC.... truck sounded awsome.. problem tho, was it ran massivly rich and flooded/ destroyed 2 cats. and it would not spin the tires. just bogged down.. I don't know what he ever did with the truck..
