So I was talking with one of the master techs at the dealer I work at, an old timer whos worked at our ford store for over 30 years now, and he was telling me that ford made 534 and 477 c.i.d FE engines that they put in the old F-600 and F-700 trucks. Has anybody heard of these? Are they the same externaly as other FE engines? Will parts swap over? And where can I find one of these monsters?
