I have to finish my basement remodel first, should be done in a week or two. Then I can put away all of my wood working tools and get ready for the engine swap.
I've studied this swap for about a year now and recently acquired a 2012 L94 6.2L with 5 miles on it. The 6L80 is out of an identically optioned 2012 Denali; it has 10K for mileage. I'm hoping the swap itself won't take more than a month or two. (This won't be my first engine swap, but it will be my first LS swap.) My plan is to keep the motor and trans as close to stock as possible. My intent is to keep the BCM in the mix for cruise and "tow" mode.
I've owned the '92 since it was 6 months old. It's in pretty darned good shape, but the tranny is getting tired. I've already swapped in a freshly built 14 bolt SF rear end with an Eaton Trutrac. 3.73 gears. Once the engine swap is done, I'll redo the interior and then I'll re-paint to finish it off.
I'm sticking with the original NP241 Transfer case. Looks like I should just need a new input gear to match the 6L80. Measuring the 6L80 it's just about identical in length to my 700R4, so I should be good with the stock drive shafts and TC shift linkage.
I've collected most of my parts:
-Wire harness from Motech complete with BCM for stock cruise control, tap shifting and Tow mode.
-New Gas tank from a 1998 Yukon. That allows me to use a '98 fuel sender/pump. The '98 uses the correct resistance range for the fuel sender. It also has a fitting for a fuel tank vapor pressure sender.
-'98 fuel sender/pump assembly
-2001 Corvette Fuel Filter/pressure regulator
-2012 truck air cleaner/MAF/intake plumbing and electric fans
-motor mounts
-Holley AC brackets
Still need:
-IdidIt conversion to cable shifting.
-Fuel lines and fittings
-oil cooler & trans cooler & lines and fittings.
-EVAP setup.
-PCV catch Can
-input gear for the NP241
-Exhaust: Still undecided. I'm getting a bid for a complete exhaust from "Get Bent" here in Portland, Oregon. Steve, the owner, has given me a ball park figure of $1800 for a mandrel bent stainless steel exhaust complete from the exhaust manifolds back. (Including two cats.) I'll have a firm price after he gets the truck on a lift and we agree on exactly what the exhaust will look like. I would love to hear any advice on exhaust you guys have!
Big question mark here: How low will the stock oil pan sit? It looks to me like it will be the lowest thing by an inch or so. Anyone who's done this, PLEASE help me out here! I'm thinking I need a new pan, but all of the options I've seen are not compatible with DOD. (Yes I am running the DOD and VVT...) Where does the stock truck pan sit on these trucks? Any pictures? This truck will be driven off road occasionally, so ground clearance is an issue.
Thanks for any help in advance! I'll start getting up pictures in the next couple of weeks.
