Can anyone tell me exactly what it takes to swap a 4.3 to a 5.3 I can do pretty much anything I'm a machinist by trade lol I just can get over the hump of just doing it I guess just not wanting to mess it up and have to spend the 5k they want to do the swap any advice would be really appreciated and thanks ahead of time guys and girls

i just put a 5.3 in a 1996 k1500. not 100% yet but it starts runs and drives. LS swap adapters aint perfect. still had to move motor mounts back an inch or so. you'll need the ls flywheel to vortec tq converter too. i went carb and thats a can of worms i regret opening. any questions let me know
