2.5" exhaust is plenty for the LS motors unless you have a lot of HP. Nice build by the way.
May I make a suggestion on your cold air intake.
90's model caddy air box. Seal up the factory opening and drill a 4" hole in the bottom of it. Buy one 4" ninty and 2 coupling from Lowes. Drill a 4" hole through the core support and bottom of air box then install the coupling from the front of the truck then the ninty and the other coupling through the hole in the box.

No real progress, i messed around and bought a daily driver yota and of course lift, tires and now a camper shell has sort of delayed progress. slowly getting back to it though. The engine and tranny is in but thats about as far as ive made it.

Andy - I like the airbox idea. May have to hit up the pull-a-part once i get it fired off.

Some progress. Got the alternator rebuilt and the belt drive on. I ordered a few odd and ends for the front clip and hope to have it reinstalled this weekend.

tinsoldier · 12-20-2014, 10:31 AM

Any update? I am about to yank mine out to do a swap.

72c10suburban · 12-23-2014, 12:02 AM

Yes and no on the progress. The complete engine and tranny is in as well as the cooling system. I still need to finish up the wiring and do the fuel systems then the drive shaft, exhaust and the tune. Its stalled out while i get through Christmas, then game on again first of the year. It at least looks like a complete Suburban now.

72c10suburban · 01-29-2015, 12:43 AM

Finally getting started back. I finished modifying the harness and started installing it today.

Nice build. Thanks for posting up this picture. I was wondering if it was possible to not run AC. Did you just have to get a shorter belt?

72c10suburban · 02-04-2015, 06:07 AM

The A/C runs off of its own belt on the truck motors. All I did was remove the compressor and bracket for it.

hubba033 · 02-05-2015, 10:50 PM

Any tips on how to remove those 2 stubborn plugs on the transmission?

72c10suburban · 02-06-2015, 12:03 AM

Basically they're glued in. I've heard a heat gun will soften it up. I got lucky and mine came out without too much trouble.

enduroride · 04-14-2015, 08:37 AM

What cam did you install in the 5.3 (part number, lift/duration) ? We are doing the same swap in a 72 LWB C10. Waiting on suspension parts to come in from Porterbuilt, figured I could do some motor work while we wait !
Thanks !

72c10suburban · 02-25-2016, 12:05 AM

Wow. Been a while since Ive been on here. Finally getting back to work on the Suburban after almost a year with little to no progress. Ive ordered the fuel pump, and will be ordering a new tank and sending unit from LMC and will be using Dorman nylon fuel lines. Ive managed to get all the cooling in and plumbed up as well as the inner fenders. Thats been it for the last year as the remaining project fund ended up buying kayaks and a gun or two. Im back on it now.

Average Joe · 02-25-2016, 06:17 PM

Good 4 you!

72c10suburban · 04-25-2019, 07:35 PM

Been a while, and progress has been slow, but this project still LIVES!

It now runs, and moves under its own power. Well, from 1 carport to the other. Ill post some updates next week when I actually get some time off.
