Could I throw out the idea of a 12v cummins swap?
5.7 Rebuild or replace with a 5.3 LS?

I would imagine that is cost and time prohibitive to most folks.

It's not even the parts to convert, but for what people want for a tired worn out 12 valve could put 3 LS's in....I'd love a 12v, but can't justify the price..
I love an LS swap probably more than most folks here, but honestly I would run what you got till it don't run anymore.
A stock gen 3/4 5.3 isn't going to be particularly impressive with power or economy in a Suburban.

Stick with the tree-fiddy. You can get a new GM L31 crate engine from GM Performance. Doubt you could justify the cost of an LS swap for your needs.

My .02c, with the Canadian conversion, probably less.
Ya the LS makes more power, in the upper RPM range. More revs = more gas used. Plus with a swap, now you are into nickles and dimes, questionable wiring, making gauges and transmission work, hunting gremlins....etc.
I would price out a crate 350 or 383, undo some bolts and wiring connections, yank the pig, reverse the process and enjoy living hassle free.

Swapping into a 96+ OBS is actually pretty easy as far as swaps go, and you can retain all your factory gauges and stuff.
There's always nickel and dime stuff though.

My 350 in my '94 GMC Burb only had 150,000 on it and ran great. But had no power for towing, so swapped in a remanufactured 383. Simple and quick, and lots and lots of power and torque. Like a new truck. The 383 has more power than the 454 I had in my '88 Burb.

I fix LS swaps all the time. I would personally stick with a 350, maybe a small cam or a 383. 6.0L only makes more power when you rev it to the moon and less at low engine speeds.

Thank you all for your opinions. It really firms up the decision. I am sticking with the 350. Now to decide if I should have it rebuilt or say "F it" and attempt it myself.
