Hey all, Welcome to me. Have lurked as a non-member for years, but decided I better make myself honest and register. I just picked up a new '66 F100 and need to get a little direction about what it is. It's a barn-find and hasn't been registered since 1998. It's very unmolested, but I'm not sure what it was and what it is now. Here are a few observations:
1) It appears that the tranny has been changed. Was, I assume, a 3-speed. Is now a C6.
2) Not sure if the motor is the stock 352, or it was also swapped. PO claims it to be a 390. Will have to determine that. My guess is the easiest way being measuring stroke.
3) The motor had a dual-point distributor and a Holley 4-barrel with a C8XX manifold, so I suspect that might have been swapped, or come with the "390" if that's what it is.
4) The rear-end is posi, but not sure if it's a limited slip or a locker. It's very close to a 3.0 as well. Not sure if there is a way to tell what type of rear-end without yanking it out.
5) Has very little rust. Worst being minimal at hood front, but nothing coming through as a hole. It had a bed gas tank, which allowed some rust-through only in the front of the bed. Easy patch for me.
6) Interior is the most baffling for me. All the panels, including the roof, door panels, and seat, are a blue plush. Even the carpet look like a factory thing. But it's hard to imagine this level of re-upholstery being done to a truck, but also hard to image Ford doing this in 1966... to a pickup. Has anyone seen such a thing?
7) Someone added power steering from, some paperwork found inside said, a 66 T-bird.
Odd Blue Plush
Here's the data plate info if anyone can decipher, or point me where I can do so. The VIN I have deciphered already, it's the other bits I need help with:
Hello DoubleOh7, That interior has been re-done, very not original. Engine very likely has been replaced, but run a 6-8" white jacket wire down one of the spark plug holes. Hold a sharpie against it while resting on the manifold. Have a bud rotate the engine a couple revs with a socket on the crank pulley. It will turn a little with all the spark plugs removed.
I plan to do the check for stroke soon. I have a brand-new (less than 1000 mile) 352 in my other F100, a '67, so my initial thoughts were to find a truck and swap the motor. This motor runs very good for not having had a tune-up for at least 16 years, so I may just sell my '67 as-is when I get this one done. That's the plan, anyway. Right now I'm focusing on getting this '66 safe and sanitary. It's getting all new brakes (dual master with booster), new king-pins, shocks, oil flushes front to rear, door rebuilds (all weatherstrip/anti-rattle bits) and making sure all the wiring is intact. Gas tank was toast, so new one is coming too. So I have a couple weeks of work in front of me.
I didn't suspect the interior was original, but someone spent a small fortune doing it. Very well done... for the time. Not to my liking though, so before I ruined some lost part of history, I wanted to make sure.

Went through Seattle district sales office. That makes it a good truck right there... Lol

C6 & 360/390 engines introduced in 1968 F100/350's. C6 has 17 trans pan bolt holes, pan has a large notch, so it looks like Utah.
Dual point dizzies were installed in hipo engines. With a C8XX intake manifold prefix, the manifold is from a 1968 390 or 428 Fairlane/Torino/Montego/Comet/Mustang/Cougar.
But who knows what the dual point dizzy came from? On the side of dizzy below the cap will be a stamped ID number, post what it is. Number will be similar to this: C5AF-12127-E
9's were not available with Limited Slip (Posi is a GM term) in F100's until 1968. 1959/67: If Limited Slip (Equa-Lok) was ordered, Ford installed Dana rear axles.
1966 F100 could have come with: Dana 44, Dana 60.2 or Dana 60.3 rear axles. Dana's have an inspection cover, 9's do not.
You can see what the original seat upholstery was, only Rangers came with carpeting. With a blue seat, 1965/66 Custom Cabs came w/a blue rubber floor mat with black flecks.
Original 1965/66 Custom Cab/Ranger headliner was grayish/white cardboard with perforations.
There were 4 individual sections: R & L cab corners, large section in the middle/front, small section at the rear surrounding the dome lamp. Clips retained the front/middle section to the rear.
The only fuel tank these trucks came with was the in-cab tank. The auxiliary tank is aftermarket, probably installed by an RV dealer.
The original 1961/69 F100/750 in-cab fuel tank (C1TZ-9002-K) contained 18 gallons.
In 1970, Ford replaced this tank with the 1970 (1970/72 F100/750 - D0TZ-9002-A) 19 1/2 gallon in-cab tank for use as a "service part replacement."
This D0TZ tank is the only one reproduced (in Asia by Blue Oval Truck Parts/Anaheim CA). Blue Oval sells it to all the other repro parts sellers and to the general public.
Thanks Bill. Will have a look more at the motor when I have some light out there.
Sorry about the Posi-slip. Wasn't aware of that (never been a Chevy guy). All I know right now is the drive-line spins almost exactly 3 times per axle spin. I say "almost" because I've got to crawl under it and make some marks, and haven't yet. Just didn't want it to be a 5.XX rear-end. It is for sure a 9" and both axles spin the same direction. If it were a limited slip, I'd have to get some friction modifier when I replace the gear oil. Maybe I can shine a light into the fill hole to see what it is. Or get one of those inspection cameras.
C6 for sure. And a truck version of it.
Thanks for the interior info. I think it probably has this blue cushy material pulled over stock bits. There are some clips of sort holding the rear panel against the roof portion. May leave that alone for now. It's perfect. Carpet is well made and fits perfect, though needs cleaning and maybe a re-dye. All of it does, in fact. Maybe someone drove it to Tijuana in the 80's.
Ordered new tank bits today from LMC. 19.5 gal. They seem to have more parts. For my Falcon and Mustang parts (I'm restoring a 69 Fastback for a friend right now) I go to NPD mostly. They don't do Falcon parts, per se, but I get a lot of parts that fit just fine. But they're shy a lot for a 66 F100 parts.
I'll keep digging into it. Motor could be anything.
