Hello fellow truckers! I just bought a nice 88 F150 2wd. The motor has been swapped out and it is a 302 or a 351 but i can not tell. Is there a easy way to tell the diffrence?
What motor is it?

Yes, the 302 is narrow, and the 351 is wide. Just look at where the intake manifold meets the heads, if its short like 4 inches its the 302, if its like 6-7 its the 351. What was orig to the truck?

The easiest way to definately tell a 351W from a 302 is to look at the lower bolt on the thermostat housing, if you would have to use a wrench to get to it then it's a 302. If you can get a straight shot at it with a deepwell socket or an extension (providing there are no brackets in the way, you get the idea) anyway, you can plainly see the bolt above the water pump on a 351W but NOT on a 302.
That's the way I tell them apart and it's the easiest way I've found.

Sweet man, the older Fuel Injection systems didnt say 5.0 or 5.8 on it. Just Ford Fuel Injection
