HELP! I have scoured this forum and the internet for the last several days. I have crawled all under my truck and have gotten every ID tag and stamp on everything I could find. I am missing the engine tag and need help identifying my engine for a minor rebuild. I bought this truck as a Farm Truck when I retire next year for hauling and building a log home.

Here is what I got:
1983F250HD4X4 XLT Lariat
VIN# 1FTHF26L7DPB07476 76
Additional number on VIN tag, below VIN
9W9VF268 4 32 K

Engine Block Stamped numbers:
D8TE OA (1978-1982 Truck Engine, 15th version of this block, A is 1st version/change?)
3E18 (built/assembled on 05/18//83)
11.8.17 is stamped at the right bottom - what is this?
No identifying marks on the Heads.
Engine is a 7.5E-EGR/AIP (electronic with Exhaust Gas Recirculator and Air Injection Pump...?) prior to EFI? Has a carb. Not sure if I got the right replacement. ??

This truck was Custom Ordered and built very heavy duty with all the bells and whistles!

Other info:
Special Order on DSO is F0479T054
GVWR 8600
Front 3850
Rear 5862 V8
Wheel Base 133
Trans Code K
Body UA4
Axel is 32 and second number looks like 17K???
Front is stamped 172 AB, 620304 on "A"
Borg Warner is stamped 13-45-039-908 with a separate metal tag stamped as:
6028 1345-21
111848 E3TA-GB
Rear is 173B 40235 70-IU
Tags under hood:
1. Has a fuel pump shut off switch #E3TE-9N831-AA
2. Carb setting (C6) for auto is:
Ignition timing BTDC 8
Timing RPM Max 800
Choke setting (auto) 3-Rich
Fast Idle RPM KD 1600
Curb Idle (auto) 650
Deceb. Throttle 1700 D
Control System RPM 50

Has a Warner Electric Power Brake
Has a Motorcraft Electric Regulator 12V ignition with External Resistor (non catalyst) #E3AE-9C485-DRN
Has a micro electric fuel pump mid way of truck 12V #125. Has dual tanks...so I am guessing there is 2? Just haven't identified everything yet!
Oil pan #E3TF66758A
Tranny calls for M2C138-CJ oil ???
OIL calls for ESE-M2C153-B (API-SE)
E3TE-6750 AC What is the best type of oil for this old engine in WA state and for hauling/pulling?

The oil pan gasket is leaking, so was going to have my mechanic replace it and the rear main seal at the same time. I am also considering a minor overhaul and freshen up this beast of an engine, but do not really know what the true specs of the engine are and/or what they need to be to accommodate for the heavy duty add ons. Is this a 350 chassis? Is this engine built more like an RV or econoline? It is the orginal engine. Also, what upgrades can I do? The EGRs appear to be in and lines present, but not hooked up to carb.
Suggestions and help please, as this is all new to me and I want this truck in tip top shape before I start hauling a 31' travel trailer and my 1949 Ferguson TO 20 Tractor over the mountain passes to their new home.

Also, any recommendations on a great shop or mechanic in Washington State that is an expert in those old engines?

Thanks!

 

The engine you have is a 460. The 8th digit is a "L" in the VIN

F26 says it's a standard cab 4x4 (5th, 6th and 7th digits)

Your front axle weight rating is 3850 lbs. Nothing special about that, that is the weight rating for the standard dana 44 hd ttb axle that came with standard cab pickups. The heavy duty front axle was the dana 50 ttb axle and would have been standard on the f350 and extended cab f250, and special order on a regular f250.

The 4th digit does indicate you have a f250HD and not a f250. The biggest difference in that is your truck should have the full floating rear axle under it. That would be the axle with the black pieces sticking out of the center of the rear wheels with all the little bolts in them.

 

Thanks Franklin!
I am about to get dirty again and double check all my ID numbers.

 

So what is this "minor rebuild" you need this motor information for?
99% of the time you tell them the year and the size (460) and you get the part needed for the job.
You talking a valve job so you need gaskets?
Once apart you would be able to tell what it is and the needed parts.
Now unless you are grinding the seats & valves and need to replace some and guides the shop doing the work can get the needed parts as they will know once into the job.
