Here’s what I got, here’s what I want to do.

700r4 It’s TV cable controlled so I’m pretty sure it’s not electronic at all.

That's what I have too. If yours is stock you may have an issue with keeping it in 1 piece. They're not known for handling a lot of torque.

I don't know what your budget is but here's a link to the EBL Flash-II you can read up on. There's lots of great info there too.

The goal is 300 hp and about 370-ish foot pounds of torque. Those seem to be reasonably consistent numbers from things I have read. That’s a concern I have two I’m just hoping it holds out. If not I can find some rebuilt ones pretty inexpensive online

In a perfect world I’d really love to just throw a turbo 400 in it and call it a day. But number one I have no idea how to make that work and number two something tells me there’s a lot of creative adaptation for the four-wheel-drive I don’t wanna mess with

Don't even need to swap the heads to get that. I know a guy that used stock swirlies, a mild roller cam, flat top pistons for 10.2:1 compression, headers and an iron intake manifold under a Q-Jet that made 325 hp and very close to 400 ft/lbs. At that power level a Q-Jet and TBI will both easily support the airflow demand.

Everybody knows a guy can you get his recipe? I don’t mean to be disrespectful but that’s exactly what I’m after is a recipe. Which Legos to put together to make this happen kind of thing.

One point for the discussion, a '92 has a 4L60, not a 700R4, and it's slightly more than a name change, but I'm not sure what the differences are. I think the changeover year was 1990, and the changeover to the 4L60E was 1993.

Recipes?
Here's what I built for my Stepside (Way Cool Jr), and I'm pretty certain it's making above your requirements:

350 4-bolt main TBI block, honed, but no overbore
Factory Vortec heads, 062 castings, no porting, no machining
Factory crankshaft
Speed Pro H345DCP flat-top hypereutectic pistons - 9.5:1 compression ratio
Speedway Motors 5140 steel I-beam rods, 5.7", bushed pin
Lunati 20080720, advertised duration 262/270, lift .507/.515
Factory roller lifters, dog bones, and spider assembly
Chevrolet Performance 12499224 LS2/LS6 valvesprings
Comp Cams 787-16 steel valve spring retainers
Comp Cams 648-16 race valve locks
Proform Parts 66914C extruded aluminum roller rocker arms
Summit 226018 Stage 1 dual-plane square-bore intake manifold
Holley FR550-511 Sniper EFI
Hedman 69440 Street Headers

Here's what I did with the old motor, and it might be right at your requirements, but I haven't fired it up yet:

350 2-bolt main TBI block, .030" overbore, no roller provisions
Factory TBI heads, mildly ported, swirl ramps left in place
Factory crankshaft
Speed Pro H345DCP flat-top hyperuetectic pistons - 9.5:1 compression ratio
Speedmaster PCE274-1001 Procomp I-Beam Connecting Rods, floating pin
Enginetech ES179R "L79 copy" camshaft, .223° @ .050", .447" lift
Summit HT817 hydraulic flat-tappet lifters
Melling VS380 valvesprings
Melling 475074 retainers
Melling VL200 keepers
Factory rocker arms
Edelbrock C3BX intake manifold (vintage manifold)
Carter 650 AFB
Summit G9200B ram horn exhaust manifolds (won't fit our trucks)

Holy crap that’s the kind of stuff I’m looking for right there. I’m trying real hard to stay with the Tbi set up just because I’m stubborn. And I put a lot of money into upgrading the stupid thing. But I love it thank you for that. As far as the transmission I am by no means an expert so I reserve the right to be wrong at any time. But I’m pretty sure it’s a 700r4. Were the 4L 60’s TV cable controlled?

 

[Erik the Awful]

Both 700R4s and 4L60s have TV cables. They're nearly identical.

Are you selling a motor? I might be interested. Although the original plan was to do this with my boy so may wanna build. I guess it depends on what kind of power is putting out and if you want to trade for a bunch of other engines and parts. Honestly it would have to be one hell of a deal though. I really wanted to do this with the boy. He doesn’t know it yet but his truck is going to end up being his. He’s 13 now by the time I get the entire truck rebuilt he will be ready to drive it.
