C is EGR, J is no EGR. All you have to do is swap the intake manifold.

Whats the difference between C and J? Can you modify a C to a J?
I don't want a 1ton pickup, I guess a 3/4 ton Sub I could live with ;)

Actually, you would.? A J-code (the one without the EGR) 6.2L
specs and drives very much like a 5.7 (350 cid) gasoline engine.
But fuel mileage is easily 50% better.

The C-code has less power (J and C are the letters in the VIN for
the engine). It is used in the "light" duty cars. I believe the
non-military Blazers would all be C-code from the factory, but I
don't really know. There were two versions of 3/4 ton Suburbans,
the one with high GVWR got the J-code engine while the lighter got
the C-code.
It seems often the cars were setup for max economy with long-legged
differential gearing - which, of course, makes them slow.
