85 bronco with 93 6bt, 518, d 60/10.25

In progress

After seven rough years of wheeling and winter driving the old bronco was getting a little rough.
Two engines and three pairs of axles, evolving from a 4" ttb lift, to a 6" ttb lift, then solid axle swap with a d44 and arb air locker, then 9" rear swap with a grizzly locker.
Tired of breaking axles and the poor mileage nearley led me to buying a psd excursion. Came as close as test driving one!. (also wanted better towing)

A friend and I had tossed the idea around of a cummins swap for some time and I finally stumbled onto a good donor truck. A rolled 93 with 220k on it . Ended up buying it for 1500.
Sold the bed/lift kit/axles and a misc thing or two for 1,100 bucks!

Motors got a new hg, toxic diesel 60lb springs, valve job etc.
mighty diesel bolts, super B, 5x12 sticks, thd piston pump, 4" diamond eye, Denny 2, diesel performance converter. 366 spring. Advanced a tooth but pulled all the way back from head. Aluminum psd intercooler .


Hoping for a good cool 325 rwhp or a hot 375.

Axles are from a 86 f350 . Sterling 10.25 rear features a Yukon grizzly locker (liked it that much in my nine inch!)

And a d60 front with James duff long arms , and broncoair track bar and bracket.

As she sits now the engine is bolted in with trans./t case.
Need to make transmission crossmember

Enough to bring a tear to your eye? That's the donor. 17 year old first car. Tipped it over first snow storm lol. Frame was bad by the tank anyways.

About 100 miles on her so far,
Seems to skip second under light throttle and shift through it quickly at wot. Did band adjustments, 1.5 turns on each screw under the pan (yes one ccw) no change maybe a little later shift from first....
Also only 37 psi under wot with maxed pump .... always somthing itll be done eventually !
