Cummins or Cadillac?

I had an IDI 6.9 Ford that sounded like a coffee can full of ball bearings due to the pre-combustion chamber design of the heads. The injectors were set to open at 1700 psi, and injector 'nailing' was unavoidable.

If you decide on the 6bt, check out Ujoint -sponsor on the Van section, as he has a screaming deal on a new one...

Why not a Chevy 5.3 out of the newer trucks? They are affordable, damn near indestructible and will drop right in with a few adapters. You can maintain the fuel injection or easily swap over to a carb. If you want to do some head work and add a cam they are a complete monster.

The plan now is:
1) Inspection and possible a complete teardown.
2) head work with 3 angle valve job with port and polish. Hardened valve seats are not required on Cadillac cylinder heads due to the high nickel content.
3) camshaft selection and installation.
4) While the engine is town down, application of Glyptal paint to all surfaces that require it. This paint stops oil and acids from seeping into the pores of the engine block.
5) Assembly and installation into the Suburban with required break in period.

These events will occur over the coming fall and winter, with installation hopefully in the spring. I want to take my time and have the machine work done by the best shops in the area. I've got quite a bit of engine here, and I want it to last a very long time.

Oh I love that, I'm keeping that one....
I have to tell the story then..
Years ago I worked at a warehouse and one of the sups, who was a vegan, veterinarian something like that asked where we were going for lunch. Happened to be Arby's, he says "Oh! get me 2 roast beef sandwiches" When we get back I asked him, "I thought you didnt eat meat?"

He looks at us, says "Its Roast Beefy!" and takes a huge bite, we died laughing.
