I have a choice to make which one would be the better one to buy I plan to drop amotor and tranny in the summer which ever one I buy?

Unless money is a factor the 92 is of course the better choice, stock mass air, better stock heads and induction system, better everything. What motor u gonna drop in?

It all depends on what you want it for and what you are droppin in there. The 92's have the 8.8 where as some 86's didnt.
