'99 4.3 vortex swap '84 c10

[cfan10]

Meant to write vortec

I know that to do the swap, I need another intake manifold if I decided to carb it. Is it difficult to use it as fuel injection in an 84 c10 original 305/350.
I plan to use the 4l60e as well, wondering about the driveshaft from the c10 mating up to the 4l60e. Also, questions about motor mounts/cross members?
Have the entire blazer to pick parts from.
Is there anyway to use the rear disc brakes from the blazer rearend on the c10? Better braking with the disc brake setup, running the same size tires on both vehicles 235/75/15

A quick walkthrough of the process of this would be greatly appreciated. Thanks as always in advance.

I just want reliability of the 4.3 in my c10 and of course the saving of gas is a factor. Blazer was hit in rear nothing major just cracked the bumper. I don't want to go out junking and buy an engine for the truck that I know nothing about. I'd rather go with is proven.
