460 What changed after '89?
I just recieved a PAW catalog and noticed almost all the kits/parts they offer for a 460 don't have applications after year model 1989. Does this really make sense to anyone? I am making the transition to BB'S after years of working with SB Fords and was under the impresssion the only differences in Ford EEC IV truck engines after 87-88 to 95 were the top end components. Can anyone shed light on why a rebuild kit (pistons, rings, bearings etc) would not be applicable to a 460 after '89? What bottom end differences there would be for a 460 form 88-95 or am I reading the catalog wrong?

bottom ends are all the same, The pistons changed somewhat in 1990 and then again with the new heads in 1993. The 93 pistons have metric rings and better oil control ring. I am not sure if CARB pistons will be the correct C.R. for EFI heads.
