Well, after spending all that time and money fixing up my engine bay, making it look new (https://forum.ih8mud.com/60-series-wagons/290221-radiator-leak-build.html), I heard some noises that made me wish I would have gone through and refreshed the bottom half of the engine as well (Engine was creeping up on 300k). Of course this started to happen a week before I deployed (Im a navy pilot on the USS Enterprise). Luckily the internet works on this ship (although at dial up speed) and I was able to research the engine options that ive been drooling over for awhile now. Naturally I wanted a diesel, but I wanted something economical and I didn’t want to turn my truck into a monster truck with a SOA (Cummins 4bt Requirement) or order parts out of country (any Toyota diesel).
After talking to proffitts cruisers and looking into the detailed work they’ve done, I decided to go with them to put a Cummins B3.3 into the 60. Reasons I went with this engine:
A. Economical- brand new engine is a little over 5k.
B. Dead Simple- Install requires minimal custom fabrication, the engine runs off 3 wires, and Is fully mechanical- No computers involved. Engine is easy to get parts for and has won multiple awards for reliability as well.
C. Fuel Economy- We will see how this one will turn out, but similarly weighted non aerodynamic vehicles have reported 25 mpg (jeep yj reported 33mpg!). I should be able to maximize this with my 5 speed and 3.7 gearing.
D. Sustainability- this engine will run full biodiesel with minimal modifications.
Potential detractor:
A. Power- 85 hp. Not too concerned about this, reported performance is on par with the 2f which im fine with. If I can get similar performance with double the economy, im on board. Torque on the 3.3 is more than the 2F (215 vs 210) which matters more in a diesel drivetrain anyways.
So I will be updating this thread as much as I can as I receive pictures halfway across the world from Proffitts. The project should be starting here soon and will be finished before I get home. So a nice welcome home present for me! Its just too bad my wife will get to drive the diesel before I do!
