hey... i got a 4.0 H.O. and i will need a rebuild very soon. i am interested in the 258 crank and rods swap, but am having trouble finding info. i know the 72-80 cranks are the best, but am having trouble with sorting out pistons, rods, and the injection tuning. does anyone have info on this swap? espically the injection part.
thanks guys.

owen
