Paid neibourhood kid 30 bucks to email me some pics.still dont know if 360 or 390.but there is a holley 4 barrel on it.looks to be original paint and such.dont know about rims and seats.

 

Not bad rig2.

Generally a 4barrel motor in a truck such as yours (i see it has AC too) the motor should be a 390, but i could be wrong, but thats what i think.

And those seat aren't a stock ford thing for the truck, the rims look to be a ford rim, just off a newer (like 87 and newer) truck.
