My '78 F150 4x4 swb Cummins 4bt build
#35
I've finally got a Cummins in my truck!!!!!!!!!!
Oh, yeah, I guess its got to be on the other end of the truck huh? Also not sure how well it would run wrapped in plastic. I made the ol' girl haul home her own heart transplant.
Here it is, sitting on the shop floor.
The flywheel housing on the engine in the pic is not the one I will be using. It's the SAE #3 style used in industrial and larger truck applications. This particular engine had come out of a van that had an Allison truck trans in it. I think I already have this flywheel housing sold to a guy over on the 4BTswaps.com forum..........
Here is the Ford flywheel housing that they used in the step van conversions...........
You can see the difference in length/thickness between the Ford style adapter and the SAE style. My first little project will be to swap out the SAE housing for the Ford style.
I picked up the Ford style housing, Flywheel, correct starter and adapter from a guy on the 4btswaps.com forum. $950.........the Ford style are getting to be kinda rare so the price keeps going up on them. Aftermarket ones are available, but they are almost as much money, With out the flywheel and starter, so I don't think this was too bad of a buy. The engine came from a local truck recycler that specializes in medium and heavy duty truck parts. I have bought a lot of parts from them over the years in the course of my job. They are always higher priced than anyone else on comparable items, but they really stand behind their used parts.
They pulled the oil pan and checked out the rod and main bearings, said they looked great. I pulled a valve cover last night and it looked clean as a pin. They said this was a lower mileage engine, but couldnt verify exact mileage.........Best part is they will postpone the 30 day warranty until after I get the engine in the truck and running.............BONUS. Like I said they are higher priced but do treat you good. I paid $4000 for the engine. Yeah there are cheaper ones to be found, but nothing close to where I live. The majority of the ones I found on the internet were on the east coast, south east US or California............all of which are a long way from where I live...........so I paid more to deal with someone local that I have done business with in the past. I feel more comfortable doing that than buying a so called "runner" off of ebay or from some truck recycler 2000 miles away that I have no clue about. Next is locating a ZF5 speed transmission. I think I have some found at one of the local wrecking yards. I went out there last week and they had 2 of them on the shelf. I also nosed around the yard and found my electric fan that I want to use. It's in the same Lincoln that my seats came out of. I think I'll go back Monday and pick up the trans and pull the fan out of the Lincoln.

No new pics.......Been busy just kinda tinkering, looking, figuring calculating and measuring on the new 4BT. I'm going to replace the front and rear main seals on it just for some peace of mind. Ordered the seals last night at work. I can get Cummins parts where I work for cost plus 10% so thats a little perk to my job......The more I look and the more I measure...........this is looking almost too easy. I think it's going to be a clean, hack free swap. Also been thinking about what I want to do cosmetically to the Cummins. I'm thinking the old dark Ford blue block, head, pan...and wrinkle black front cover, aftercooler etc. ??????????? Maybe polish the aluminum valve covers????.........I'm going to wait to start painting etc. until after I have gotten the trans, clutch, situation figured out as well as any other items I need to repair or replace. I dont want to get it all prettied up then start skinning up all the new paint and powdercoat while I'm wrestling it around to figure out the clutch situation. Hopefully will be picking up the transmission tomorrow!!!!!

I'm not really going to start playing with the Cummins until after its in, running and I have all the new build "bugs" worked out and see how it actually performs. I drive this truck every day so I need to keep the downtime to a minimum. I know that 120 HP doesn't sound like much, but, It should be comparable to my stock 351M. The thing you need to remember about diesel power is torque. (Torque starts the world spinning........horsepower keeps it spinning) Stock this little motor will produce 300ftlbs. @ 1700 RPM. I'm not going to be doing any heavy pulling with the truck. It's basically my back and forth to work vehicle with a few long road trips thrown in for good measure. I'm going more after fuel mileage, reliability, drivability and a touch of "cool". I'll be starting the actual swap after the weather breaks and I can start riding the Harleys for transportation. If I decide to do injectors at some point, I'll keep you in mind.
