OK , that truck being an F700, I wasn't sure if Ford offered the 429 in that or the 800 F series for that matter. They did in the Louisville 800's. Either way, if it's a gasser, it's a V8! How's that?
My dad had damn near that exact truck, it was an industrial 429. To my knowledge, the industrial 429 and the car 429 are semi-different animals...and the indy 429 isn't very desireable.
