what is the advantage of this. if i decide to ditch the jac yj, ditch the energizer plan, get a used pump and intake fully loaded....since i wil have too do extensive glasswork anyways.....i just want to hear the pros explain the advantages and how much work it will be. i can do basic glass work but this would be the first doing anything of this caliber. also with the pump set back would i leave the engine in the original spot and run a longer DL. while saving for a jetaway?
