The cheapest route would be to do a mechanical carb conversion. You'll need a carb, coil on cap standalone HEI dizzy, and a fuel pressure regulator.
If you want to keep the TBI you can get the correct injectors, the adapter for the TB to the carbd manifold, and a v8 dizzy.

iv already got bigger injectors from a 454 tbi and it had an adapter already on it and srry to ask but wat is a dizzy? so really i got everything i need i just needed to know if it would all work and wat all i would have to do to make it work
ya i figuered that out after i thought about it lol srry bout that so am i able to use everything from the 4.3 on the vortec motor?
Your going to need the Dizzy, cap, rotor, and plug wires obviously. You'll need the heavier injectors you have. You'll need an ecm from a 350 truck and further your going to have to have a chip made for it. Check out tbichips.com.
I believe the only sensor you'll need to change is the knock sensor.
