My dad and I have owned a total of 8 F-series trucks. The 300 is a great engine for a truck, stock it made about 10hp less than a 302 but it made a lot more torque. In fact, you'd have to go above a 351 to get a higher torque rating. Do you have a picture of it? or could you give some of the detail like the grill, fuel door type? 73-79 are VERY similar
73-77 had same front grill. 75 (I'm pretty sure) and later had a fuel door on the side where pevious models only had the cap. Interior is the same.
78-79 had its own grill (better in my opinioin) that was shared with the Broncos of those years. The grills are interchangable. The interior has subtle differences like the steering column.
If its pre 73 it has a ridge on the side of the truck, don't know much about those models
EDIT: I see you added an attachment but for some reason it won't show up for me.
