hey so in addition to my 93 I might be trading my built 351w for a 1987 Ford F-250 6.9l 4x4 its blue no rust great shape and has a c6 auto tranny not sure on gears or if there open or posi but its a regular cab 8ft box and the ac doesn't work but Il fix that eventually. but for those of you that have 6.9s is there any thing that's different from the 7.3's.

 

Same engine, a 7.3 is a bored out 6.9.

There are a few small differences, larger head bolts, weird fuel filter with a screw on bowl/water separator, but the same engine all in all.
