4 barrel intake on 360/390?
Hey all, new to the board. I have a 76 F250 hi-boy, which is pieced together to say the least. Not sure if I have the 360 or 390 mill. The guy I bought it from said it was the 390. The carb spacer on the intake is for a 4-barrel, with an aftermarket carb. I heard that only some of the 390's came with the 4 barrel. The question is what is the intake on this motor? Is the intake the same for the 360 and 390? Is it the same for a 2 or 4 barrel? Is it possible that the intake is for a 2 barrel 360, with a 4 barrel carb spacer? Also, what's the best way to find out if it's the 360 or 390? Any and all help would be appreciated, as I'm a newbie to these Fords. Thanks.

You'll need to describe the intake more, find casting numbers if possible.
I'm not sure they ever put 4V setups on 360s, but I also beliveve that there are few if any factory 4x4 390 setups.
The bets way to determine if you have a 390 is to measure the stroke or ID the crank. Do a search in this FE forum to find several methods of measureing the stroke.
Now , with the age of these trucks there is often no telling what somebody else has put in the truck.
I think the 2V intakes have a smaller intake opening, so it would require an adapter for a 4V carb on a 2V intake.
