Chris, I believe it is later than '92 as to all, I know some had them, but I think it is '96 that all had rollers. Some of the transition years had "roller" blocks (have the bosses for the lifter spider & front thrust plate) but had flat tappet cams. I helped a friend do a Vortec head & roller cam swap in his '95 truck. It had the roller block,but a flat tappet cam. His was a shortbed 1/2 ton 4x4. It had 66,000 miles. We used a GM kit, it came with the intake,one exhaust manifold,ect. Lorne

Mike, To use the factory parts, you need to have a roller compatible block,the cam,lifters,lifter spider,pushrods,front thrust plate. There may be a few other parts, timing chain gear,distributor gear,ect, without research that is all I can think of, Lorne

What makes a roller cam a roller cam is the fact that it has roller lifters.

and a profile too aggresive for flat tappets.

Did some checking and that is correct, 1996 was the official across the board for rollers in trucks.  Cars got them earlier.  I have seen a 88-95 pickups w/ a roller before factory though.  Guess it was like everything else GM, hit or miss.
