I bought a 69 F-100 and I am sure it has a big block in it. I have been told it looks like a 350 modified but I didn't think Ford even make one. I need to know what I can do to locate the type of engine that came with this truck when I bought it, with the engine still being in the truck...If possible.... The cab and the truck bed is a 69 make and it sits on a newer frame. My next question would be how and what is the best way to locate the type of frame it sits on. This truck is a 4x4 with many mods... I need help...

One more question...
I have a 460 out of a 1985 ecoline van....anyone know how hard it would be to swap the engine/trans? Mods etc?

Let's start from there...thanks in advance..
