Re: 5.3 into 72

Did you have to mod the frame rail for the lower mount compressor?

No modifications to the frame at all.

Re: 5.3 into 72

Seems like it's been too long since my last post here. Recently I've put new window felts in the vent window channels and it stopped the annoying window rattle these trucks can develop. That's all the work I've done! Here in about two weeks I'll be putting on new wheels and tires. 20x10 riddler 695s with 295 40 20s on the rear and 20x8.5s in the front with 255 40 20s on the front. Next up I'll be tinting my windows. I bought some pre cut tint. I'm going with 35% on the sides and 5% on the rear. I am keeping things legal for the state of NC. Then I'll add in my pressure transducer switch and binary switch and get my vintage air charged. Hopefully by the end of summer I'll be adding a Detroit truetrac to my rear end. This should all make for a great summer.

Re: 5.3 into 72

Well, the windows are tinted now. Already, there is a temp difference in the cab, and that's without the AC. Next week she gets new shoes and I should be finishing off my VA system.

Re: 5.3 into 72

Got the new wheels and tires on finally. I realize it's the typical setup, but I love it.

Re: 5.3 into 72

Looking great there Jesse. I'm helping a friend with a '68 frame off and LS swap. I've been following your thread so it will help me see where all the pieces go a little further down the line. Is yours a single rail fuel line with no return? Thanks Ed...

The rail has no return. The return is on my Fuel pressure Regulator.

Re: 5.3 into 72

Congrats!!! Kool looking truck.
How was the clearance with the Gibson headers and your shifter linkage?
Are you running original shifter linkage or after market? Thanks

I'm running Lokar shift linkage and there are no clearance issues with the headers.

Re: 5.3 into 72

Truck turned out awesome! Very good work! I have a couple of questions- could you post a pic of the backside of the truck so we can see how far the tank hangs down? Also, did you have to alter the tank to use those hoses with the AN fittings?

Thanks!

Re: 5.3 into 72

I thought of another question. What was your old tranny, TH 350? I am wondering if you had to cut the drive shaft with the new engine/tranny combo. Thanks.

Re: 5.3 into 72

My old trans was a TH350, but I used the driveshaft out of the donor vehicle. An 07 Suburban.

Re: 5.3 into 72

I haven’t touched this post in a long time. Today I installed an Eaton posi carrier with the 3:73’s that were already in the rear end. I lucked out and the factory shims put the backlash right where it needed to be. It’s nice to have some traction now and not be a one tire fryer. I think next weekend I may install tear disk if I can figure out the booster/master combination I wanna go with.

Re: 5.3 into 72

So tomorrow I start the cam swap on the 5.3. I’ve been waiting for years to do this. I went with the Truck Norris cam from BTR. My 5.3 is DOD, so the heads are coming off to replace the lifters. I have an autocal from black bear performance with a bae tune loaded for the cam. Hopefully everything goes smoothly.

Re: 5.3 into 72

Since you are doing a cam swap are going to upgrade the valve springs and push rods. I would. Depending on your engine mileage I would also replace the plastic lifter guides. They are cheap.

I upgraded the springs, put in a set of LS7 lifters, new lifter trays and I upgraded the rocker trunnions. My 5.3 HAD the DOD, so the heads had to come off and the lifters had to be replaced. Now there’s just the process of tuning with black bear performance.

Re: 5.3 into 72

So today I installed a cpp booster/master/prop valve. The factory booster bracket looks awful and I needed a disc/disc mc since it m going to be installing rear disc brakes. Hopefully by the end of the week. The new booster setup looks so much better. I also used captainfabs brake booster bracket. It worked out great.
