5.7 in a truck

I have two 5.7s (2 to make one good one) and a nag from an 07 charger. Would this combo go into an 2x2 88 pickup without major hassles. Original engine-trans are very tired (250 thousand)
Got the wiring harness but no controller
One more thing, is the electric pump used now strong enough for the Hemi injectors?

Holley has swap parts for that truck

no the TBI pump wouldn't be up to the task, but that's an easy fix.

Holley has a lot of parts for swaps but I don't think they have nag1 into truck, probably not too hard to use their stuff to make it work. You then need the Sound German Automotive $1000 controller kit plus the shifter from the car.

What I’ve been reading since posting, thanks. A lot to gather over the winter.
