Hello all, looking to learn more about my truck. I'm looking into performing a complete engine rebuild, never done a diesel but I've done a few Chevy 350s. Not sure what knowledge carries over and what to let go. I see a lot of threads worth looking into here, and I thank anyone who drops a line wishing to point me in a good direction. Thank you!

Welcome.
Going from a 350 to 6.5 is no biggie. Definitely a manual for specs counts more on diesel.

Is there specific things you have questions on?
You want an overview comparing them to understand better?
Just let us know and we are glad to help.

Welcome.
My thoughts are depends on goals and budget. Is the truck worth it? 350 is dirt cheap in comparison! Why rebuild? Hi milage, blowby, low oil pressure? Loss of power? Want to tow better? Any current mods or upgrades? Injection pump?

Should get at least the better water pump later model iirc 99+ gm spin on fan. Might be 2000 - the balanced flow water pump. The rest depends on above?

Welcome! Yes, why rebuild? You will find these are a throwaway engine and it's sometimes cheaper to buy a new longblock than build a used one. I have gone through a few 6.5's and 6.2's rebuilds and simply add good rebuildable (crack free) engines are hard to find anymore.

Pics. WE WANT PICS of the somewhat rare Yukon 1994 diesel!!! :woot:
