No factory FE Ford Econoline vans. First year that anything larger than a 302 was offered was 1975, which is the next to last year that FEs were used in PU trucks. So pretty much every Ford engine, besides a FE was used, 6 cylinder, 302, 351W, 351M/400, 460, V10s and diesels, were used, and I imagine the 4.6 /5.4 mod motors as well.
