There was never, ever a factory 360 with a 4 barrel. Every one was a 2 barrel.

 

This truck must of been special ordered with a 4 bbl. This 360 FE had the factory 4bbl intake and carb. There was no modification done to this truck.

 

So did my 1968 F250 390, but it was the manifold off the 390GT along with the carb and heads, all with Ford factory numbers. And someone swapped that 4 barrel into there as the factory never did it. To do so would have required them to have a seperate engine code so the parts weenie would be able to find the right parts. I've seen dealers do it, but the factory, NO!

 

Okay, if I may ask, where did you get that information? The reason I ask is that I just got a 65 F250 and the VIN comes back as a 352 with a 2-barrel, but I can see a 4-barrel factory manifold with an adapter plate with a 2-barrel carb is attached.

 

positive it's a 4bbl and not just a phenolic plate ? Just asking.. no need for hatchet ehh folks LOL

 

Right, the factory which has access to any manifold they are making, used an adapter plate. You believe in the 100mpg carburator too. Oh yeah, everyone knows that nobody every change out an engine in any 1965 model year vehicle. I have an old 1968 F250 that the VIN says it is a 360, 2 barrel. But there is a 4 barrel manifold on it so the factory is lying with that Vin number and it really was a 390 4 barrel with 390GT heads, intake and carb, so the owner could cheat on his insurance. Wake up and smell the roses.

 

I think maybe I came off sounding diferrent than I intended, sorry. I wasn't questioning the validity of your statement, Bear 45/70. I wanted to know the source so I could research my vehicle. I appologize if I sounded like I was bringing out the hatchet...
Anyway, the history of this truck is short. My father in law gave the truck to me. It sat parked for several years after the original owner, his brother, passed away and left it to him. My father in law swears he knows for a fact this is the original engine, and it was rebuilt twice, but never exchanged. I would not of thought otherwise, except that I noticed significant modifications, such as the aftermarket adapter plate, some headers and air cleaner. I made an assumption that, being a F250, the engine was probably a 360, less likely a 390, and the modifications were the result of an attempt at better gas mileage. I ran the VIN and discovered the original configuiration is quite diferrent from what I expected, then read your post, Bear 45/70, and concluded my FIL was mistaken, and the engine was likely swapped at some point. I'm curious to know what engine it might have now. The source of your information might tell me what FE engines came with a factory 4-barrel, and that may give me a clue to start with, before I measure stroke.
Again, sorry for coming off like an @$$, it was totally unintentional.

 

Well you weren't the only one to get it wrong, so I apologies too. I have several service manuals, both Ford and aftermarket and they have the Vin number breakdowns and the engine codes in them. The are several places on the net that also do the breakdowns. But on an older truck or car, only God knows who changed what in them. I've done way more than my share of changing for that matter.

 

No harm-no foul
Is there a way of determining which engine it is, other than measuring bore and stroke?

 

Unless the original factory tag is on the dist. hold down bolt, not really.

 

I'll look, but I doubt it's there.
Thank you very much.

 

More info - The 360 is mainly a de-stroked 390. The difference is the rotating assembly (crank, rods, pistons ) When I rebuild my 360-4V, I'm boring to .040 over and changing to a 390 crank and rods but getting a new set of 360 pistons. With an RV cam and a 1' spacer under a 700 Holley and with long-tube headers, I should notice a BIG difference. For my $$, that's the biggest bang for the $.

 

You will need new rods and +.040 won't make it a 390, it take +.050 to make a 390.

 

OK now you got me all confused! I thought the 352 and 360 shared the same stroke of 3.5", but had different bores:
4.00 for the 352
4.05 for the 360...which would be the same as a 390 bore???

 

Correct...........
