TBI 454 vs. TBI 383

Just pondering a few things and seeking a little input...

Looking to get a little more juice out of my daily driver '88 K20 Suburban and I'm undecided between building a TBI 383 or swapping in a TBI 454.

Not looking for crazy HP numbers, just looking for a little more oopmh for towing and a little more giddy-up for the green light.

Seems like a 454 would be a little easier from a swap perspective, meaning I could pick up a donor rig and swap everything over. Whereas the 383 would involve some trial and error as far as TBI tunability goes.

Any thoughts?
