    Engine Swap to stroked 6.0 (408) and general vehicle refurbishment

    Well, good news and bad news... I got the car started today. Its LOUD. Maybe too loud. Although I just have the y-pipe clamped together at the moment. But I think the sound is coming from the front, not necessarily the exhaust, so I'm not sure that getting the permanent Y-pipe is going to...

    Here is a shot from today, once I got the intake manifold on. After that picture was taken I installed the alternator, all of the radiator hoses, and my AirRaid CAI. I have to say I was a little disappointing with the AirRaid kit. First, some of the fasteners they sent were the wrong thread...

    Alright, time for another update on the progress with this project. I got the engine into the bay back on the 16th. I didn't get started that day until kind of late, and then had to wait for help, but eventually my wife came out to the garage, and it didn't take us to long to get the engine...

    2012 suburban disappointment

    I recently pulled my engine as detailed in another thread. The rear bolt on each exhaust manifold was broken. I'm not saying that this is "right" or "acceptable" or "normal" but it does seem to be very common on these vehicles. Similarly to Rocket Man, I'll be using ARP bolts when I put the...

    Yes one was included. It was the white plastic stock one.

    There is one more thing that bears mentioning, and I am putting it in its own post so that it stands out... I purchased a TCI flexplate 399757. It is marked "this side must be toward engine". I installed it the other day as marked, but thought it didn't look quite right. Today I installed...

    In addition, the transmission rebuild is complete (in about half the time that I was quoted by CircleD no less!), and I drove down to Houston to pick it up. My new torque converter took about a week longer than the transmission, but it was finally finished late last week, and CircleD shipped...

    I had a lot of work to get the engine ready to go into the Tahoe. In particular, the front and rear covers and seals, as well as the windage tray, oil pickup, and oil pan needed to be installed. I bought a Milodon 31507 low profile oil pan, which I like because is has kick outs on the sides...

    Texas Speed finished the engine, and I drove to their facility to pick it up. Man, she's a beauty/

    Engine Swap to stroked 6.0 (408) and general vehicle refurbishment

    I have not posted in a while because i have been busy between work and working on the Tahoe, but progress has been made. I spent quite a few hours working on sound deadening the doors. I purchased Killmat, which is similar to Dynamat, but significantly more affordable. Eventually I will do...

    Engine Swap to stroked 6.0 (408) and general vehicle refurbishment

    I pulled the driver side head off of the old engine just to see if I could see anything wrong in the vicinity of the #7 cylinder, which was giving me a lot of misfires, and fouling plugs. You can see that the build up on the #7 piston is a different color. In addition, the electrode end of...

    Seth - The stuff I am using is this: https://www.amazon.com/gp/product/B07FW86XV6/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1 I bought it in several sizes, 1/4, 3/8, 1/2, 3/4, and 1 inch. I think I also got some 1.25 inch. I probably didn't need all of those sizes, but this is the first...

    Engine Swap to stroked 6.0 (408) and general vehicle refurbishment

    I've been looking for little projects to keep myself busy while I wait on my engine and transmission. One thing that I noticed is that the factory looming on my engine wiring harness was looking pretty rough. It was brittle in places, and sections were completely missing in other places. In...

    Well folks, big news - the 5.3 is out of the Tahoe! I've spent quite a bit of time over the last several days pulling connectors, unbolting accessories, labeling things, and cataloging them. I've put every fastener I've removed into labeled zip-lock bags and have a computer spreadsheet of...

    Well, once I get the Tahoe back on the road I guess I'll find out how I did with my differential rebuild. I think everything was in tolerance and put together correctly, but I'd hate for you or anyone else to give to much of what I have to say about it to much credence until it is tested! I...

    Well, I made the 260ish mile drive down to Houston to Circle D, and dropped off my 6L80E, and after talking to Glen there for a while, I'm glad that I did. The only downside is that he says they are possibly as much as three months out to get it rebuilt, so it looks like I'm going to be waiting...

    Does anyone know the purpose of this? It was bolted to the back of the driver side head. i can't see any purpose to it, other than to block access to the oil pressure sender. I think I have lost skin on this $%^&er every time I've had to mess with that sender. I am planning on NOT putting it...

    The next phase is the transmission. I am going to have it rebuilt by CircleD. I called and talked to Glen, and he was very helpful and recommended their 2.5 level rebuild, so that is what I am going to do. Taking the advise of a couple of members of this forum (much appreciated) I removed the...

    Once the new bearing was in hand, I used the inner race from the bearing I ruined with my press to press the new bearing onto the pinion shaft. I did one more depth check just to make sure the shims still provided the correct depth with the new bearing, and it was good to go. I moved on to...

    I haven't updated this thread in a while, but I have been making lots of good progress. The race that I last mentioned ended up bring a royal #$%^er to get in. I tried the freezing method, but it coincided with a drop in outside air temperature, and my first try was unsuccessful. I may not...

    Believe me, I thought about it. But I am all cleaned up, the wife and kid (and the neighborhood) are asleep. I think I'll just have to wait for the morning.

    After that, I pounded out the pinion gear. And then the real fun began. The pinion gear bearing races were a nightmare to get out. I finally got them, but it took WAY more pounding and was WAY more difficult than YouTube led me to expect. And then getting them back in...I finally got the...

    Once that was out, I decided to pull the old axle bearings and seals. Does anyone know the purpose of the little plastic ring with the castelations on it? I ask because if you look closely you will see that it was slightly damaged and one of the little castelations was broken off. I'm not...
