I have a 1969 f100 ranger with vin# F10FRF54045. I looked at two differant books and they both say the fourth letter is the engine code so mine would be "F". Both books say this is a 391 engine but I didnt think they put that engine in a F100. It has a 4bbl on it too and my books dont list a 390 4bbl for 1969 but they do say the 391 has a 4bbl. Any ideas out there???
Now, I'm gonna be a little more realistic and say that there is no way they EVER put a 391 (4v) in an F100
Although engine codes did change when an engine was discontinued they generally were consistent. I don't have a 1969 book, but according to the 1970 ford shop manual, what you have is an inline 6 cyl, 170 cubic inches, with 1barrel. I'd be willing to bet that is what the truck originally came with
Mil1ion,
Yeah, I know it sounds crazy, I have never laid eyes upon a 391, but thats what my book says an "F" code for engine will be. Then again, I have never seen a truck that was manufactured in San-Jose either. Who knows? I was just trying to help the guy out and state that my info also indicated that his truck had a 391.

Hey rusty, there are known examples of mis-stamped door data plates. Why don't you take a look at the top of your front rh frame rail, about two or three inches in front of the engine crossmember. The serial number is also stamped at that location. Maybe use a scotchbrite pad to gently clean up the area and see what you find.
To further identify the engine you do have, check the block casting number and date code above the starter on the side of the block and get the casting number from the intake manifold as well. Got me curious now
mk,
I checked the frame rail and the vin codes match.I didnt have any luck finding the casting numbers on the block yet but im going to keep trying to find them. But I did get the numbers off the heads and intake. The heads are C7AE-A. The intake has two numbers 6F21 and C5AE9425C. The only thing I found on the block so far is the 352 on the drivers side front with a 16 above it. The carb on the truck looks to be a stock ford/holley 4150.

Heads are very common `67-early `68 FE heads, found on cars and trucks. Intake is a `65 unit, from a car most likely. Neither of these items are for an FT, which the 391 was.
The "352" on the front of the block was common on most pre-`70's blocks, identifying it with the first 352 engine.
Look for the date code cast in on the drivers side, below the oil filter. A small pad at a slight angle from both the bottom, and the side (skirt) of the engine at the very front of the block will show it.
