I'm glad to know these 6.5's are still available.

Thanks so much for this follow-up video. I had been periodically checking for it.

As a owner of a 98 2500 6.5 reg cab/box i enjoyed your video.

Nice work. I glad you took the tome to post a few videos on it. I have had my Navistar block bare on the stand for couple years. Just about done collecting all the goodies and these videos are good motivation for getting moving on it. That plus my current motor in the suburban is consuming coolant. 😅

A 4-Stroke Detroit Diesel painted the same color as the 2-Strokes. I freaking love it!

Well done. Looks and sounds great

Well done! Just finished my Optimizer build about the same time you did. You should get a oil temp gauge. I noticed the oil tends to get hotter then the coolant. I added a remote electric oil cooler. I am considering an HX35w just to help with the egts not increase boost. Any future plans for it?

I love that Alpine green

Me too, i think it looks super cool

I need to know the exhaust setup in detail please ^_^ sounds perfect. About to swap a 6.5 into my 79 C20

If you don’t mind me asking where is the nut for the stud on The thermostat housing?

Good job man.

Just got my 6.5 do you have links to the oil cooler kit as well as an upgrade on a turbo kit I was thinking of the hx 35 or 40 but was told. They sell kits cause they are not bolt on as well to the heads and egr delete and vacuum pump delete kit ?

Where did you find the optimizer as a bare block?

Thanks for sharing! By chance what ac delete pulley did you use?

Yup I’m done messing with the 6.2 and the 6.5 Cummins brother. Do the swamp.

keep the seats. Just take them and have them re upholstered. They look like they would be worth it.

I've got to ask what kind of fuel economy are you getting now with the rebuild and you've been running it for a few months. Do you have any numbers even ball park would be good to hear

I think somewhere around 16 but to be honest I havent paid much attention to it. I will have to report back when i calculate it. Havent been driving it much with fuel prices rising so much

How do you like the promax heads? I’ve heard mixed reviews. Did you notice any gains?

So far so good. Didnt notice anything performance wise from them. We will see how they hold up in the long run. Have only put 1000ish miles on the fresh build

So far its still running good. Got A/C working and fixed all the little issues it had. Havent been driving it much but ive put about 2500 miles on the rebuild mostly pulling trailer with my tractor on it. Still havent had the chance to install hx40 but im getting close to wanting that extra power and lower egts. Will definitely do it this winter if i dont get to it this summer.

I think I have same oil cooler line kit it’s nice but yeah the fit is bad needed longer lines

You might want to check out a dual thermostat cooling system. It was used on 1997 and newer 6.5's. Much better coolant flow.

@@averybryant yes it's getting cool out specially here in Saskatchewan I just got a 96 Chevy Silverado K1500 6.5 turbo with 500 000km on it runs great was parked for 4 year sounds like a have a small knock the previous owner said it never did that when parked. They parked it cause the trans was starting to slip in 4th so I bought a parts trucks 97 I'm switching the 97 transmission transfer case dash and whirring harness over to the 96 as I like the 97-00 dash better and I'm switching the 96 manual 4x4 over to the 97 pushbutton 4x4 system. He claims he put a rod through the oil pan on the 97 6.5 yet I no dents in the pan so was thinking of yanking the motor and rebuilding it but I'm worried it will be a waste of time as it'll be a squiter block not that I'm scared of them oil change oil change oil change and the will live for ever as far as I'm concerned. When you pulled your block appart was thee any cracks ?

Sounds like a cool project man. Yes when I took apart the old engine every single main web was cracked, some were super bad too. It was a not squirter block 599 also. I got this block from someone who got it from a machine shop that tore down and inspected them. I think I posted one of those “shorts” videos of the old block cracks on my channel, or I probably showed it in the tear down video
