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?

Nice thing about a 6.5, decent fuel mileage. Cheap to work on. Problems are known, most are very easily fixed. Power, yeah a bit on the under stated side compared to todays motors. STILL, a 200/400 motor is nothing to sneeze at, and they will overall pull upwards of 8-10K without issues at reasonably decent speeds etc. Keeping them cool is the main issue.
I went from the pre97 cooling mods, to the post 97 with dual t-stats, high gpm pump that is about double the water flow, and a 7 instead of a 5 blade fan with a different fan clutch, made a lot of difference for me, IE I could use the AC vs not and still have lower engine temps.

The big thing about the Peninsular over the stock 6.5 is the lower compression pistons and large turbo. By putting more air through the engine, not only can you inject more fuel/get more power but higher air volume also provides for much lower exhaust gas temperatures and therefore less demand on the cooling system. We installed the 7 blade fan and high flow water pump as well. The Peninsular diesel uses a steel crank and the new 6.5 blocks are much stronger than the old blocks as well as having heads which provide better cooling and are much less prone to cracking. The truck is fairly quiet and I believe it must be putting out over 300 HP by the way it pulls.
