Git er done
So far we are impressed with the new Peninsular 6.5 diesel in the old truck. About 27 mpg (imperial) and very good power. Maybe we need a couple more tires under it though?

Do as I did to my 96. Put an upper 6 leaf instead of the 5 pack, with all the leafs being 1/16" thicker. Gave me an 8500 lb pack instead of STD 6400 rated spring pack.
I've also heard good things about the penninsular diesel for 12+ years now. If I still had the 96 and that motor went out, I would get one from them.

What is the difference? I just know from 3 crate 6.5's being replaced they have thin cylinder walls.
From about 99-2000 on or so, The 6.5 has been poured from the same plant as the Navistar V8 diesels, with a higher nickel? count in the block. Which has made it stronger. Reality is, the stock or penninsular diesel from this time on is better this way.
But even before this time, the Penninsular diesel had a slightly lower compression, ie instead of around 21-1, lowered to 18 or 19-1 as the Navistar V8's had, as does the cummins and most other turbo diesels. THis allows them to handle the higher pressures from the turbo, and generally speaking, allows this motor to last longer.
The majority of diesels with 22-1 compression were in reality, never designed to be turbo's, including the idi6.9/7.3 navistar v8's. ALtho many did turbo them.
