Dustin, I'm looking forwards to seeing your project on this, sounds like it will be a good rig when it is done... More intercooler is aways a good thing!
Keep us posted when you get going on it.

Had the flu for the past week. I'm pretty backed up now so the 70 goes on hold again for a bit.

Dang, seems like everyone had the flu last week.

I am just recovering from it as well.

Dustin is this still a cummins?

Yep, it's a 97 Ford 12 valve cummins.

Nope... At one time Ford owned some stocks in Cummins, but was never a big deal, since Cummins has bought their shares back. Ford owning Cummins was one of those internet rumors that as the legend goes... the Ford guys started

You have been able to order a Cummins in F-550's and larger for some time. Maybe even F-450's? But that is it... just an option.

No difference.... a Cummins is a Cummins regardless of the application. You can find these motors in many trucks, busses and countless other applications.

Yeah, they come in quite a number of different configurations.

The most common non-dodge 5.9 cummins engines are the ones used by Ford and frieghtliner in the big F-series trucks and FL-70's.

The Ford/freightliner engines all have the low mount exhaust manifold that is necessary to make a clean install in 73 and up Fords with AC. The Ford engines also have Ford alternators and special AC pumps that work very nice for Ford swaps. The downside to them is they have 5 gallon front sump oil pans and high mount fans. You have to factor in the cost of a dodge style oil pan and fan hub if you get one of these engines. Regardless of where a 5.9 came from it's still a cummins. The Ford engines I have are all 175HP CPL1550 motors. Dodge used the exact same CPL 1550 engines in thier 94-96 5 speed trucks.

The cool thing about the cummins engines, really another BIG reason why they're so great for swapping, is because they have countless variations and you can get virtually any sort of accessory bracket, motor mount or transmission adapter to fit whatever you have and the stuff fits really well and works right. You can fit a dodge motor in a Ford, but the accessories don't fit as nice as they could and the throttle linkage isn't as nice.

So it would be easier to find one out of a Ford? Other than the fan and oil pan anyways? On the cummins do you have to run a motor driven fan or can you run a flexi lite fan??

Mike, weigh the costs involved to get the setup you want and go with the engine that is the best deal for you when it's all said and done and the engine is configured the way you want it.

For the 72 and older trucks or the 73-79 non-AC trucks the dodge exhaust manifold is a real nice fit and seams to make more power than the ford/freightliner manifold. The ford style manifold also likes to crack in half under really hard use and usually doesn't make it past 300K in a heavy truck.

Learn what the main differences are in these engines and what exactly it is that you want. For example, it would be pretty stupid to buy a first gen dodge rotary pump 12 valve engine to swap into any 73 or newer Ford that has AC and you want any real power from. The dodge accessory brackets are useless for you, the dodge exhaust manifold won't fit and the rotary engines just don't do it like the inline ones do.

For the engine that's going in my 70 I'm just running a Ford alternator and power steering setup off a Ford chassis 4BT, no AC to worry about. I've ported the head, installed a 4000GSK, valve springs and haven't decided which injectors/delivery valves to go with yet. I'll be running a 3 piece aftermarket manifold and likely a single S300 turbo and a straight 4" pipe.

For my truck I didn't need the parts that come on the Ford 5.9 engines, but those parts are in very high demand and easy to sell. I mostly just like how it says FOMOCO on the engine ID plate instead of dodge.
