It appears I may need a new engine for my 95 SWB 3.9. Mine overheated, but went an additional 35k miles before what I fear is the block failed. So, I am somewhat concerned about getting a used engine, as you never know the history. Anyone have any experience with used engines? What would be best, another 3.9, 4.0 or 4.2, or finding a good block and using my internals?

PT - Thanks so much for all of your help and respones to my PM's...I took the head off today, looks fine, I'll have a machine shop verify, but I am planning for the worst so I'd like to start researching for a replacement engine. I'd have no problem building one up if I new the block was good. My Crank, Rods and Pistons "mic'd" out well within specs 35k ago, so I would assume they are still good, and could use those parts if I could find a good block.

Will Tillery, Dominic Perrodeau, Pendy. Any one of them might have an engine for you.

In spite of my fears, the supply of engines seems to be holding steady as long as folks don't continue blowing them up.
When you get done, send me the old block.

I have a very nice long block out of a '95 RRC SWB that I'm selling for $400. The engine ran well before the truck was parted out. I'm in CT if you are interested.

I have a complete 6.2 sitting here ready to go. Only thing missing is the alternator. :evil:

Tdculp,
Where are you located?

I have a complete 3.9 sitting on a pallet but it's in Nova Scotia

Mt Pleasant, SC

If you like the truck pony up for a used 4.6 short block and a crower cam and a 4.2 LWB chip.

I have a dozen engines to choose from.

I have a few as well, but the shipping from Abq would probably be unreasonable. I'm sure you can find something closer...like Kansas.

We don't paint our parts at Pendy.:rainbow:

Oh yeah? I beg to differ.

Might not paint them rainbow colors, but you do paint things...

Cylinder head checked out fine, so I guess it is a problem with the # 3 cylinder in the block. Going to start returning emails and calls now to locate a replacement long/short block. Just out of curiosity though, is the #3 cylinder prone to failure as I cannot see any evidence of the liner shifting???

Just because you can't see any thing with that cylinder does not mean that under engine operating conditions, pressure/temp, that it might not begin to leak.
