Very nice! Thanks. One last question: who orchestrated your 4L80E swap? Do you have a build thread or some decent documentation of the details of the swap? There is a lot of interest in this swap for the GMT900, and yours is the first I've encountered on this forum.

Well, I performed the 80Eswap myself. The only thing I wasn't able to handlewas the Segment Swap of a Van OS onto my T42 TCM.

It was actually very simple. Cut the ears off the side of the 80E case, and get a custom converter that has a 4L80 style converter housing, and a 4L60 style front plate.

The trans has an adapter plate on the rear so the Transfer Case bolts right up, get an 80E style dipstick and PATC also sells a custom crossmember to take up the difference in length while retaining the stock mounting locations. Cut rear driveshaft to length (front has lots of meat still), enjoy.

And the dyno is a secret. Mainly because it was rigged.

That is sick! I always liked the idea of the KB on the L92 but they don't make a kit for us; I assume this is a Camaro kit with some wizardry regarding the accessory pullies? Sorry for mucking up the thread, gentlemen, but this setup has really gotten my attention.

Exactly! Well, I lucked out. Theres just enough clearance for the alternator and steering shaft down below, and the power steering pump has almost identical ratings between both truck/Camaro.

Then basically the truck water pump works just fine, 8 ribbed, with OD pulley. But oh my god..... Extending and re-routing all those wires..... and moving crap around. It was interesting to say the least.

Honestly, I'm thinking about going twin turbo... It's extremely hard to keep the Kenne Bell IAT down. Otherwise it's one of a kind!
