It can be done on pre-Vortec engines, but requires a 24x conversion kit, MPFI intake, wiring harness, distributor, coil packs, etc.

Look over on Gearhead EFI about the 411 swap also. I've seen Lextech active there in the last few months, and there are several others knowledgeable about the swap and tuning.
