79 f150 cummins street truck
My truck started as a stock 79 f150 351w ac c6 9'' rear.
truck is a none restored original rust free truck, only body mods are to the tailgate roll pan an paint..
The motor an tranny came from a 1995 dodge 2wd.
motor is a 12v cummins, p pump factory rated at 160hp
tranny is a non electric 47rh overdrive with lock up
upgrades to the motor include
flowed an benched p180 pump, 5000rpm governor springs, delivery valves, mack rack plug, 5x18 injectors,
fire ringed head with titanium retainers upgraded spring.
block is 40 over billet pistons stock in all other areas tho.
turbo is a 66mm set with 1to1 drive pressure at 50lbs of boost, waste gated manifold running into the down pipe, running a boost controlled nitrous fogger system to clean up the rest of the fuel at the top end an a progressive shot to help spool the turbo at the bottom end.
intercooler is the stock dodge upside down with a few inch's cut off the top
tranny we built in the barn with the rest of the truck, added up graded clutches steel drums an planets billet accumulators upgraded valve body late model input an out put shafts. with a billet converter
the rear end is a 9'' with a full spool, 3.08 gears
im going off the top of my head so if theres anything else you wana know let me know..

im running cut springs front an spring flip rear, but its almost on the stops front an rear so im going drop beams an a c notch in the rear along with massive sway bars.. the turbo is a mix match pile of used parts off some pull truck.. its been pretty tuff, bearings lasted about 2 years, just rebuilt it..
as for mpg at 60mph no boost babying it iv got 36mph running the truck normal an having fun I stay in the 25mpg range, an running extremely hard it will eat a tank in a quickness..
the suspension is my last stage of the build, im doing I beams in the front with bags an valves on the bags with massive sway bars ( cant go mustangll or crown vic due to the 1200 pound motor. rear im c notching with 4 link on the out side of the frame with a pan hard bar an massive sway bar.. the truck will sit 2'' lower than my pics at ride height an I hope to have added performance , rite now it drives like stock, doesn't hook at all an corners like a tractor rite now its a fun truck, roll into the boost at 60mph an burn the tires as long as you hold it, has no function at all tho an is a hand full at highway speeds when it breaks loose

Why are you going four link outside of frame rails, just seems like it would limit the width of the tire you can fit back there? Im sure you have your reasons, just curious is all.
I enjoy the cummins motor in my other truck, but the truck make wont be mentioned here
Looking forward to your updates.

Nice. I'm in the process of building my 80 F150 2wd with a 12V and NV4500 5 speed.
Not going for anything near that wild, though. My goal is just a simple, daily-driver type build, using as many stock items as possible.
Looks like the engine was a rather tight fit in the 2wd chassis. I'm curious about the front crossmember too, as I've heard the 65-79 2wd front cross member has to be notched about 2" for oil pan clearance.

That is quite the unsuspecting sleeper.
Looks like you raised the floor tunnel, did you also notch the engine crossmember?
Love the rat rod truck with compounds.
Have you dynoed the truck?
Looks like very clean work and seems you have quite the knowledge and love affair with diesels.

The crossmember is un cut, I did notch the oil pan for clearance and the rear valve cover is close to the fire wall but dose not hit. I used a set of ford Cummins motor mounts an just had to do some persuading. As for running on the dyno, I haven't got a chance to do it just yet. I hope to be around 600 to the tires tho.

I wish I had more build pics but the motor swap was done in a few weekends, the original home for this motor an trans where in a 78 chevy 2wd half tone, my buddys an I built a few years back, but the frame couldn't handle the power or weight of the motor so my buddy sold the truck, keeping the motor an trans for another truck, as he lost interest we decided to put the motor in a real truck so the plans was in effect, it was a rushed build do to money an being out in the weather.. the truck has been together 2 years now an is slowly becoming what I had envisioned..
