    I love seeing people using these. I have a 6.5 599 block in my 1991 FJ80. I pulled it from my 2500HD a couple of years ago. With 180k on the engine, the cylinders still had good cross-hatch. Bottom end looked like new with no visible cracks. I did find cracks between valves on the heads at the rear cylinders. I cleaned it out and put new heads on with ARP studs. I added all of the updated cooling components along with the best fan and clutch I could find. HX35 turbo, 4 inch in, 3 inch straight out. I'm only running 15 lbs of boost. It's a little hazy pulling hills but EGTs are good and it has plenty of power for the Land Cruiser. I can get nearly 20mpg on the highway with 4.10 gears, 35s, and full-time 4wd through the 4l80e.

    My first experience with the 6.5L Turbo was while working at a Chevy dealership. We had to pick up a small fleet of trucks we had to sublet for modification. I chose a route back which took me over the back roads with some seriously steep hills. I was amazed at how the truck I drove pulled up the steepest hill, it kept accelerating as we climbed which wasn't an easy task for most vehicles.
    I also wound up seeing a fleet of these trucks towed in with blown engines. The truck shop mechanic simply stated much of this was probably due to what he called misuse -- driving it like a gasoline engine, winding out at high RPM or excessively lugging it. Otherwise he insisted it was a good engine. Over the years, with the experiences I've had working in the automotive repair industry, I have to agree; if properly maintained and not overly abused, they can be an efficient and durable engine.
    And who doesn't love that old school "clacking" of an old school IDI diesel?

    Nice to see another Suburban with a 6.5 getting souped up! Hopefully someday I can get my hands on a p400 or optimizer myself. I thought about a Duramax swap too, but decided to stick to older and simpler. These engines get a bad rap imo, they came out of the factory with a few issues, but once sorted they're solid as anything imo.

    Been watching your 6.5 rebuild video series over and over. I would love to do what you have done there! But I would at least do one thing differently: SPEED OF AIR PISTONS!
    Guys, you gotta check that out! I contacted DFC Diesel (who offers SoA pistons for their reman engines) about getting SoA pistons for a 6.5 and they said they could do it. The 6.5 is not listed in their product lineup but they were willing to do it anyway! And then I thought you guys would probably definitely maybe hopefully like to try that out!

    💪Definitely worth the wait. It's crazy how much time has past by since the 6.2 build. My oldest boy has been eyeing up my old burb, I showed him different parts on it that I fabbed up gosh it must have been 25 or 26 years ago, your name came up when I showed him the rear shock mounts on the frame. Steve's business was just taking off then and in those days information came from word of mouth, Four Wheel magazines, or phone calls to someone for answers when no one was building parts like beefier rear shock mounts for a Suburban. Alot has changed since we both first built our Suburbans. I think its time my boys and and I build a new engine for my Burb too. The 6.5 build, the video, and time spent with your dad, "Priceless". Thanks for sharing this build David, looking forward to the next part. 👍

    Helpful helper tip: If you want grease on engine parts that won't be assembled for a while, ATF assembly grease is a great option because it withstands pressure and dissolves in oil. But if you don't have that around, plain old Vaseline petroleum jelly works just fine. It stays in place and readily dissolves in oil. It doesn't offer much resistance to pressure, but as long as your oil pump is working, it should be fine.

    Great video, awesome to see you and Pops working together :) And no such thing as labeling too many things when building an engine! Thank you for sharing the small details like tool part numbers. Did you remember to gap your rings before installing? A new set doesn't guarantee proper clearance
    Every P400 part is still available except for the block or full engine. The best head upgrade for a 6.5 is to run P400 heads, they have hardened valve seats and will resist cracking better than the stock Optimizer heads or any aftermarket one
    Also a word of advice to anyone installing timing gears- Don't assume they are plug and play. There's a recent aftermarket set that have the dots off by one tooth and several engines have had valves hit pistons and trash engines. At a minimum use the old timing chain set dots to align the cam and crank before putting on the gears
    Thanks for giving the 6.5 some love, they definitely have a trash reputation because of GM's penny pinching but when built and maintained properly can be a very reliable and easy to work on engine

    You can never go wrong with the old diesels. Sure they left much to be desired hp wise. They had a real chance at lasting 500k+ miles though and made enough torque to be fantastic work trucks. I have a modern 2011 duramax and while I love it, I love my 93 7.3 IDI turbo way more. Its probably gonna hit 700k miles in the next few years.

      @WillometMotorFab Glad I found the channel too! Funny story. One of my best friends growing up in high school acquired a 92 or 93 silverado with a 6.5 shortly after graduation. The thing had a bad compression skip and was blowing a ton of white and blue smoke. Pulled the head on the bank with the dead hole and found a severely scored cylinder. From there we pulled the oil pan, removed the piston from the bad cylinder, honed the crap out of it till all the vertical lines/scoring were gone. (Really should have been bored but he was broke as was I). Put the original piston back in with a new set of rings, buttoned the motor back up and the thing ran like a top! Albeit it always had a little bit of piston slap on that cylinder until it warmed up afterwards. Ended up driving it for 4 years after that going back and forth to Northern Arizona University and it was still running pretty decent when he sold it! 6.5 DDs aren't as bad as people make them out to be.

      The P400 has that girdle, which is pretty nice and fulfills the original Detroit deep skirt design. But, they don’t make the P400 anymore (as of this writing).
