HWH- Awesome build and keep the pics coming. I love the LS motor swap and Blazer tank in rear !!
I live in Texas also and l searched for a couple of years before finding a 1991 V3500 crew cab about 6 months ago.  Its a factory stock truck with a big block and power windows and ice cold air. The truck is super low mileage, but spent its entire life on a ranch. So far I have installed 6 inch front lift, new bearing and u-joints in front D60, pulled motor and installed new oil pan gasket and intake manifold gasket, motor mounts, Hooker headers, 3 inch duals with flows, tranny cooler and completely rebuilt wiring harness.  I've got a 4 inch shackle flip for the rear and a suburban interior ready to go in as well The only beat- down is this truck has a Gen V 454 with TBI and I don't have a lot options to build power.

I have owned 2 other square body crews, one with 12 inches of lift and 40's and one with 15 inches and 44's.  This will be a driver with 6 inch and 35/36's.

Nice copperhead. You have the holy grail truck 1991 was only year had 4l80e to np205. Everyone wants that adapter lol. Luckily I had the round pattern np205 and not figure 8 so made it easier to adapt got my adapter from northwest fab. And yea when I bought truck had 350 TBI. And did a lot of searching and there's not a whole to do to get a lot more power out of the TBI motors. But hey we all got to start somewhere. When I first started this build I was going to do the Cummins swap but more research decided not to. I just think in the long run ill be happier with ls swap. I'll get more pics soon posted I have been taking pics every little step.

ill get lots more pics posted where i left off in post above. but here are some as what stage im on now getting ls swap and painless wiring harness. High mount brackets used for a/c compressor to move from bottom to top of motor. Headers worked out nice clearance from frame which is good. Saw people notching there frames to fit others. Didn't want to do that. Got porcelain spark plug wires to help from heat from headers.
