I'm starting this thread to document the parts, costs and work done, as fully as possible. Ill be adding info as I go along. Im doing all work myself except for the manifold back exhaust. Work will begin in March 2024 and be finished in time for our trip to Ouray in July 2024. This by no means the the only way to do this. It's just how IM DOING It so...yea.
I bought this LX in November 2022 (day one is the first pic). It was purchased from the original owner with 360,000 miles. Its factory "triple locked" and came with a ton of service records. A great start at $3500. Yes. $3500 for a rust free Texas one owner. SCORE.
I replaced all the leaky seals with a Wits End Kit (RIP), replaced the locker actuators and started on a few fun things:
OME J-Spring lift with their shocks, stabilizer and caster bushings.
315/75/16 Nitto RT's
Front and Rear Trail Gear bumpers. Added a winch and some Amazon lights up front and welded on a 4xInnovations rear swing out kit with table. (I can share more on that if anyone is interested)
I decided I hated puppies, ripped off all the plastic cladding and roof rack, filled all holes and Raptor coated the truck in Metallic Charcoal. It shimmered in the sun and my 5 y/o daughter named it Sparkles.
That brings us to now (Mostly). The 1FZ FE still runs strong and smooth but burns a little oil as to be expected. And the transmission is still strong as ever. But, we tow a 2900lb pop up camper. That with the weight of the truck and its gear leaves more power to be desired.
Wife gave her blessing and so the next stage begins.
I had originally settled on doing a LS but after some more digging I decided on doing an LT
I chose an L86 (6.2) mated to a 4x4 10L80. I like the power the L86 produces (420hp/460tq). That, plus the 10 speed will make sure its always in the sweet spot. The 10L80 also has a granny 1st gear (2nd for that matter) of 4.70:1 for 1st and 2.99:1 for 2nd. Compared to the A343F with a first gear of 2.80:1. Thats a final 1st gear crawl ratio of 48.09:1 with stock gears. (I think)
I discovered Torfab's 80 Series Gen V LT Kit. I cant speak highly enough of him. He answered tons of questions and was so fast to respond. His kit offers 100% bolt in application. You start with a 6.2 or 5.3 with a 4x4 10L80 or 8L90 and use his adapter to mate it with the LC80 Transfercase. You are able to utilize the factory oil pan and truck style manifolds. His kit also places the transfercase where the factory driveshafts can be used. Tor is also building me a custom fan shroud and mounting kit which will house factory style PWM fans that will be controlled by the Gen V ECM. I know Ill have great support once I begin the install.
I also ordered a factory Harness rework, Gen V DBW pedal, ECM Tuning and his "Muscle Car Module" from SwapTime. Mitch over there is a wiz with these things. He specializes in C10 truck conversions but he seems very interested in breaking into the LC world with these LT conversions.

MORE TO COME!!!
