Trying to Verify My Engine
So back a couple months ago I bought this 1965 F250. The guy who I bought it from (who'd had it for decades) swore up and down it has a factory 390ci in it. As we all know, that would be impossible, and the VIN decodes as a 352ci. However, now that the weather is warmer and I have started working on the truck, I see that it has a non-stock C6 trans, and I am thinking that instead of the 352ci that it was born with, that it perhaps has had a 390ci dropped into it at some point. The interesting thing is that the passenger side valve cover has an emission stick on it (barely) that kinda looks like a 302ci sticker. I know it's tough, but can anyone ID this sticker? I looked around the internet but didn't find any 390ci sticker that was orange (they all appear to be white and blue).

1965/66 FE pent roof shaped valve covers are plain. 1967/76 FE pent roof valve covers have Powered by Ford embossed on them.
My 1965 F100 352 had painted gold pent roof valve covers with no decal on them. Truck was assembled (1/1965 - San Jose) and sold new in CA with the mandatory PCV System.
1958/64 FE valve covers are rounded without holes for oil cap/smog valve, have an oil fill tube at the right front of the engine.
1961/64 with PCV: Smog valve threads into a boss on the intake manifold in front of the carb.

Here's my valve covers. The few original 1966 I've touched didn't use a sticker but silk screened it on. You can see Dennis Carpenter lists that decal as 1960-1965 F-Series. Must have been cheaper to just silk screen it than to slap on a decal - and maybe held up better? Who knows. Dimensions are slightly different on the silk screen than the decals.
