2006 Sierra 2650 Magnuson install and 8HP swap!!
Finally got the engine and transmission in, the 8HP70 fits perfect with zero trimming required. Ended up having to use a 4L80e crossmember with the tab flipped around to bolt it in. Now for the wiring!

Can't wait to see this think run!
Accessory Drives
I want to use the low, forward, right side AC compressor mount in tandem with the low left side alternator mount and no power steering. Is that as straightforward as is sounds or are the idlers and tension going to be a problem?

@John Mobley since the 551137-LS76-3 relies on an alternator being mounted above it on the cylinder head, I would not recommend that exact bracket. Instead look into the 551137-LS74-3. Since it uses the 4 rib belt spacing, the placement is very similar, but not reliant on other accessories. for the alternator, the 551887-3 kit would work, but may be a little difficult with belt routing without power steering. instead look into the 551668-3 kit paired with the 551550 belt and idler kit. These two parts in conjunction with a factory tensioner will work perfectly together.

This is my new, legit Tial waste gate. It cost almost 5x as much as the knock off one I was running made by Summit. (Which I already replaced once) I pulled the Summit one out last night and found it was stuck open, as suspected. Which very likely cost me my hero pass on the dyno last week. Worse, if it can stick open, it can stick closed which very likely is what killed my old aluminum block on Memorial Day. Digging deeper it was very likely heat soak that killed my Summit WG. It’s mounted below the downpipe, under the turbo and behind the manifold. I’m betting the silicon are melted inside of it. Where I don’t doubt the Tial mv-R will work better it’s also destined for a short life in that crucible. So I’m going to add water cooler lines. To make that happen I ordered ICT Billets new (?) Steam port kit with the AN4 fittings and will make some PTFE lines to loop out from the steam port to the water gate and back to my water pump.

I ran a Tial for 10+ years on 28psi at the gate and it worked flawlessly. Good choice!
