unless you really need the power then the stock motor will be plenty, i mean i had a 4 banger that was 110/100 flywheel i think and now the 5.3 with the mods listed is around 315ish flywheel. in a light vehicle it does well. Normal driving i hardly go over 3500 rpms for shifts and it moving when doing so

with 1 tons and the 6.0 youll be fine unless its mud buggy or a hill climber

i bought quick connects to go from the jeep pump/regulator nipples to the LS fuel rail. i picked up a returnless fuel rail for the LS motor, this way you only have 1 fuel line to worry about and the jeep regulator does its job
i did add a single walboro to the jeeps pump assembly

i have the injectors scaled for what they would be at 50 psi which is what the jeeps system pumps out, myself has been together 10k miles without one issue from fuel system
