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.
No 4-barrel 360's
No 4x4 390's
You can use an adapter to put a 4barrel on a two barrel intake, but it doesnt work very well.
Gtex is right, these old trucks can and more often than not do have anything.
