7k is almost expensive for a slightly built up fox. I almost paid $6500 for a 351 w/alum heads LX with a brand new TKO 600 in it. it had a brand new paint job and a bunch of other junk. If I weren't over here, I probably would have bought it just for the engine and tranny. I already had a buyer for the roller at $2500!!
Here's a whole slew of foxbodies with 351's.
