New to the forum from Iowa

1989 Wagon. Gray on gray. Had a 350 swapped in. I pulled it out the first day it came home. Replaced it with a 6.0L amd 4L80E. Dakota Digital VHX gauges for 77-90 Caprice. I also installed a 96 Impala shifter/console and leather Bonneville seats.

Well, that underhood shot took me by surprise.

Look at all those wires though, my goodness! That looks like a lot of work to sort those out.

Nah, it wasn't too bad at all. I DID lengthen all of the wires to be able to route them behind the engine and along the inner fender. I need to cover it up with loom so it looks better now.

Awesome engine swap,really caught me offguard as well.Bet it runs pretty good with that 6.0,is it stock or modified?

It is stock for now. I was thinking of a cam swap this spring. I just wanted to get the stock engine in and running to make sure I had everything right. THEN I can start changing stuff.

Very nice job and welcome.

Nice! Welcome. The older I get, I am more nostalgic for Boxies.

very nice! didnt think the truck ls intake would fit under the stock b-body hood. at least, not the bubbles bodys. nice wagon!

It did fit. I had to take off the evap solenoid.

Very cool sleeper. Nice job and welcome.

Did you have access to a complete parts truck for the drivetrain swap or did you piece things together? Factory PCM?

I bought a pullout from an H2 off ebay. It had the ecm, drive by wire gas pedal and module, and got a 2004 truck transmission. I used HPTuners to turn off most of the un needed stuff in the computer.

You need one of those motors to run against that wind in Iowa... Welcome. Jeff

Wow, a sleeper indeed. Nice swap and i dig the Dakota dash
Pete

Wow, that's cool.

Nice Wagon. I'm envious of that dash.

Great sleeper, which gear set did you choose?

Sticker says it is 2.93s, but when I punch that in HPTuners, it doesn't match my phone gps.

I want to go with 3.42 or MAYBE 3.73s.

3.73:1 is the way to go.

How did you integrate the hydroboost with the new powertrain?

The donor Hummer had hydroboost, so the pump reservoir had the extra return fitting. I swapped my vacuum booster with a 4500 Chevy hydroboost unit and an Astro mounting plate. I THINK I used all of the 4500 lines, and found a 9C1 cooler loop at the junkyard.

Does the Hummer come stock with hydroboost or is the engine modified.I always thought hudroboost was for engines with cams making very little vacumm.

It was factory with hydroboost. I had a 1ton 2000 Chevy dually with hyrdoboost on a 350 Vortec.
