8) charlie, i owned one of those once. it could have either the 144 or 170 six. the front suspension is far removed from your falcon. the van uses a straight axle front end instead of the SLA the falcon uses. one day i hope to own another. and yes, a 302 fits nicely, and in the 63 and later ones you can put in a 351w or 351c. the 61 and 62's are a bit harder to swap a V8 in. however a 300 would fit real nice in that.
