how much is a new crate these days? I have done some checking and found some manufactured 6.5's for 3500.00 with the same 36/100,000 warranty on them. I am just putting info aside for if that day ever comes I need it.

That's 52000mi\year, so you couldn't go wrong with the crate engine - if it has not been sitting in a warehouse for 5 years.

You'll want a 2005 engine, to get the good stuff.

Thats a good price.I saw them on a G.M. sight today for over seven grand.I think the stamped number ,top,front,drivers side,on the rail between the head and valley describes the year G.M. put it together.Along with cu.in.and option code.What numbers on the block tell when it was casted i have no idea.I wish i did know.

You have to watch out for GM crate engines, friend of mine does a lot of 6.5 work at a dealer and he told me they are still using up there leftover engines.

The guy I bought mine from had the engine replaced by the dealer in Dec. 2000. The part # on the invoice is 12457640, lists for $7279.40, net cost $4532.00

I bought a crate 6.5 from a local dealer for 5k found out it was the early block, did not know the difference at the time. 7k plus is what I was quoted for the late model block if you could find one. just going by what was told to me.

I'm not sure about price differances from truck to van /school bus engines. I was priced $6800 for an F long block last fall.

If I was buying a 6.5 engine tomorrow for my truck I would really take a hard look at Marshall Engine for 3500.00 with a 36/100000 mile on it. I would be interested in what blocks they use and IF they could be orderer with 18.1 pistons also.

Yep, that's the good Hummer block. Cast by International/Navistar. For 5,800 I would go with that - good price, good engine. Have 'em put the new aftermarket oil cooler lines made by Lubrication Specialists so you won't have another failure like that again.

GM still uses the same crappy aluminum crimp fittings on the oil cooler lines, and its just a matter of time before they fail again.
