Cousin has a 1960 Rambler wagon too!! I don't know what engine it had in it, but he recently put in a mostly stock Ford 360ci (360 de-stroked and differant heads basically) from a 1967 Ford Pickup and it will move! Fastest wagon I've ever seen in my life...
P.S. - Farna, that is the biggest post I've ever seen in any forum except some of the classifieds where people have one million things in one post for sale.
