What's My Engine?
Hey, Y'all.
I'm new here and need help solving a mystery.
I recently acquired a 1964 F-100 with a straight 6 cyl engine.
The Spec page on the owners manual lists 4 engines, 3 6's and an 8cy.
A previous owner has circled in pencil the 223 cid
but, I need to replace the clutch and I want to be sure I'm asking for
the right part. Is this the 223cid?
The trucks ID plate has a letter code for the engine in the warranty number.
It is J.R.
The ford dealer says its too old to find
The ID plate says the net horsepower is 114 @ 3600 RPM
the spec page shows
144 cid engine Brake horsepower 85 @ 4200
223 cid............B H P 135 @ 4000
262 cid engine B H P 160 @ 4000rpm
292cid 8cyl
Anybody know the 1964 engine code JR?

It is overwhelmingly likely to be the 223. The 260 was seen rarely and usually only in big trucks. The 144 was rare as well (did they ever really put on in a truck??). Hopefully, someone can verify this using your engine code. I would not be bothered by the disparity between the rate horsepower on the VIN plate and in the owners manual.

144's were only in Econoline vans or Falcon's, never in a F-series truck. That was a lazy Ford dealer. He gave you a load of**** when he said it was too old to identify. He has the 64-72 parts on Microfiche and it's right there. He probably doesn't have the 57-63 ones. "J" is the engine code. It's a 223 I barrel. The "R" is the assembly plant code for San Jose, Ca. Post the entire vin number and the second row info and we can decipher it for you.

I also have a 64 F100 with a J VIN code. I've never torn it down to measure, but 223 parts have always fit EXCEPT when I put a clutch in it. O'reilly's parts book was specifying something with different dimensions. BTW, in trucks this old, there's no telling what's been retrofitted over the years. For example, my dash has an "overdrive" cable that doesn't attach to anything, with no provision on the tranny for attachment, either.
We measured the old one and they had a replacement in stock at a nearby location. Sorry, I don't recall what the listed application was for, but I would recommend buying your replacement clutch only after you have the worn one out for inspection.
