Do you have any pictures of the hot side? Did you just do a log and a crossover under the trans?

I'll post what I have. It's an On3 performance kit originally for a '99-06 Silverado. Using Tejas Steelworks mounts moved the motor up and forward enough that the crossover flange on the PS cleared the frame. I fabbed the crossover and downpipe. Thats the DP that comes with the On3 performance kit. Obviously I cut it up. 4" SS exhaust (originally for a 1st Gen Cummins Dodge) 4" DP" /> 3" --> 4" DP
Mostly. Custom cam ground for this setup. Stock bottom end with Gen 4 internals with rings gapped for boost. 317 heads with BTR springs. 4l80 has a performance build with a Hughes converter.

I'm super excited to see how it run! I was very positive on this combination from the very beginning.

I too have a crew cab dually that I am ditching the gutless 454 for a turbo LS. Tosding in a mild, boost prepped 6.0 LQ4 with a GT45 mated to the NV4500 5 speed already in the truck.

Short answer: I don't know. I bought a '16 Sierra to pull my boat with and haven't tried with the '77 yet. In the process of swapping turbos at the moment. Couldn't control the boost with the S366 and a single 44mm wastegate. Moved up to a 78/75 with a larger exhaust housing. If that doesn't solve it, I'll add a second WG. Truck pulls like a freight train but i haven't been able to finish tuning it because of the boost creep.
I must admit this is interesting. My biggest concerns will be octane and fuel usage. Just some random thoughts here.
Running WMI would probably be a good idea. Turn it on when towing to keep temps down and detonation away. Unless youre running 93 and mild boost and timing? e85 would be awesome, except you would probably need a larger tank. LOL.
Small turbos would be great for spool up, and while youre not realistically going to make use of peak torque at 1600 RPM's, small turbos will spool faster and for a setup like yours, spooling fast to get the load moving is what its all about. Only drawback if you make torque too low you'll run the risk of bending rods.
Or a duraburb.....but goddamn those are expensive.
Any better shots of WG placement? Looks like your placement may be the issue with the creep. A single 44 should do the trick IMO. What are you tryign to regulate the boost down to? Have you tried pulling timing to limit the power a bit? I'm planning something similar with a 5.3 soon!

WG is not ideal (90* to flow initially then back in the direction of flow) but it is part of a kit that works with the turbo that ships with it (which is not what i used but is what I'm swapping to). Plan was to run 6-8 psi with the ability to run 10-12 when I want to.

Love the setup. Been thinking about doing this to my 79. The bbc in the truck now is burning oil and isn't the most reliable motor out there. If I did the swap I'd def b doing it on a strict budget. I was thinking either a 6.0 or 5.3 with a gt45 on a log type manifold. I'd probably run a sloppy stage 2 and some deccapped injectors. Only plan to run 5-7 lbs of boost. All this would b attached to the th400 already in the truck. I hope to stay below a 3k budget all in. Idk if this is possible but would b fun to try. This is the truck in its current state. Just got done painting it.
