Hi guys. I bought a 66 F100 less than 2 weeks ago. As per the vin, it originally came with a 352. Seller told me a previous owner swapped in a 460. He is not a car guy and didn’t care to ask. It runs well so that was enough for him. I also tracked down the guy who sold it to him. He says it’s a 429. But he didn’t swap the engine in either. He sent me pics and he def bought it with this engine in it. Trail goes cold there. It’s a 3 speed auto trans which I assume is a C6.

I’m not looking to go fast and it runs fine but it’s killing me not knowing the displacement. From what I’m seeing, I believe this engine is wearing most of its OE stuff. I also believe it to be nothing special, it’s got OE EXH manifolds with EGR’s plugged and what looks like a factory 4bbl cast intake. With that said, I looked up many posts regarding FE engine ID. I got some numbers.

Pass freeze plug area behind starter going vertical:

D1VE A2B

there is a “101” on block by fuel pump.

Heads are DV3E A2A

if I’m right and this engine hasn’t had its heads swapped, do I have a smog era 71-78 460?

Trans has casting # D7AP-7000-AA. I’m aware that prob doesn’t mean much. It shifts good and the fluid is nice and red. The metal tag I’ve heard about is not present on the trans



Tranny

Last few digits of block

Plugged er in manifolds

Can’t stand this. That chrome is going.

Head


It has a durapark already and a 600 cfm Edelbrock. I believe I have the “bad” timing set and since everything up front is leaking oil, I’ll change that out and reseal/ detail things. Other than that, he plan is a tuneup.

 

Use a wooden dowel through the spark plug hole to measure the stroke.
3.59 = 429
3.85 = 460

 

D3VE-A2A are '73-'74 429/460 heads.

Some discussion:
https://www.ford-trucks.com/forums/7...460-heads.html

That thread also talks about the block casting number of D1VE being a common 429/460 block.

I think your transmission casting number should be "D7AP-7006-AA"

Just a garden variety C6 for the 429/460,

However, the 429 for cars was discontinued '74, so IF this engine transmission combo was brought over together, that would put it at '77 or so and make it a 460.

(The truck 429 came later, and you do not have one of those)

The plugs in your manifolds were for air injection via smog pump, not EGR.

So if it runs good, run it.

yes I mis-typed the trans number. You can see the right # in the pic. Sort of what I figured on the rest. Yes it runs good. May need some carb tuning and maybe I’ll swap the timing set.

 

Truck 429? 🤔

 

Thanks for the responses. I’m more confident now in my initial assumption that I have a 460 out of some kind of late 70’s land barge.

 

370/429 replaced the FT and Super Duty engines in '79-'81.

 

Ahh, I forgot about FT and SD

 

If it has an external counter weight on the harmonic balancer it would be a 78 and up 460.

 

That would be a D9 block. He said it's a D1 block.

 

I have a PO installed 385 series in mine as well. Don’t judge it by the exhaust manifolds since fitting headers would be difficult. NTL, sounds like you’re on track with your current assumptions. I would measure the stroke to be sure.
Your plan to just drive it is a great one. However, if you're going to dig into it a little, I suggest posting on the FTE 385 forum. Specifically, Dave McClain is a real 460 guru. You might consider looking for advice on timing set, and cam to go with the existing heads.
BTW, your distributor is currently hooked up to ported vacuum. I'd move it to manifold vac when you get to your tune up. Ported was an early smog device designed to increase chamber temps during idle to burn exhausted chemicals. It should idle better and cooler on manifold vac.
For your upper radiator hose, if you want to replace that universal unit, I scoured catalogs and found gates p/n 21026 fits pretty well. Another member used 22692, and I believe he had to cut it. Looks like you have an aftermarket radiator, so unsure if it will be the same. Here's pics to compare the geometry to yours.

 

Great info, thanks! and I'm jealous of your engine bay, can't stand mine with all that chrome. I don't care if it looks stock 1966 but I do prefer stock looking even if its the wrong year. I also have that stupid modern looking aluminum rad, flex fan. it's all so wrong lol. I'm got a 70's stock air cleaner and valve covers I'll paint up nice and I'd also like to find a decent clutch fan- maybe even a cold case rad as they look pretty stock when painted. Love your washer bag setup too.

 

A good surface roughing, some less than glossy black paint, and much of that glitter will go away.

 

Mine's in an acceptable spot for me at this point. I'd like more time to wrench and tinker, but mostly I just drive it as-is. I think cleaning up the cables and hoses is good bang for the buck.

 

Looking at the block casting number it shows "D?"1VE
Therefore according to the page linked below, the "V" is for Lincoln. I think you have a Lincoln 460, unless a 429 by chance.
I have a 429 with the D9TE casting, and my engine builder said it was a 429 when he disassembled, it's from a '78 E250 Van.

Like mentioned above, measure the stroke to know for sure.

I have a '66 engine C6ME block in a '71 F250. _ _ _the "M" is for Mercury, and the "E" is for Engine. (series code).
it came with the '66 Merc 410 in it already.
But, you must check stroke to know for certain which crank the engine is hosting. LoL

The 4=pages in the link above are very helpful.

Vans were commercial highway runners, so they were equipped with super tall gearing.
And, if you are running the interstate a bunch, why run the long-stroke 460, when the shorter-stroke 429 runs along easier.
That is my guess as to why maybe Ford badged some 460 commercial truck engines as a 460, when in fact they were a 429 in disguise.
No-one would know unless measuring the stroke on the 385 series.
Also the stroke varies between the FE series 390, and the 410 / 428 engines.
What fun.
