I just picked up a 1973 F-750 dump truck with a blown 391 in it. Local to this area since new apparently, and yet never seems to have seen a winter (?) very little rust. I sourced a running 330MD for it, so I will probably go that route, as 391s are scarce around here.

Anyway, it has east coast style wheels, a 5-sp (clark?) and what looks to be an eaton 2-sp axle.


F75FVS08286
134 6 F754 418 GHM
24000 556043

I can deduce the 24k weight rating, the 134 inch WB and I know 391 and Kentucky truck.

Any help would be appreciated, it will join my 73 F-25 and my 79 F-600 Crewcab as soon as it gets the engine swapped.

 

You omitted the TRANS code, GHM is the AXLE code.

F75 = F750 (gas).

F = 391 4V

V = Kentucky Truck Assembly Plant.

S08286 = 1973.

134" Wheelbase.

6 = Bright Medium Blue.

F754 = F750 (gas), 24,000 lbs. GVWR

418: 41 = Black Vinyl / 8 = 81A Standard Cab.

GHM:

GH = Eaton model 17221 Two Speed Rear Axle / 6.50/8.87 / 18,500 lbs. Rear Axle Capacity.

M = Ford 7,000 lb. Capacity Front Axle with Power Steering.

556043:

55 = St. Louis MO Ford District Sales Office, where the original selling dealer ordered the truck from.

Yeah, sorry the trans code is M clark 5-sp, I think, same as my 79 F-600
