Slant 6 in a 99 Durango?

Absolutely hate this thing. Ran across it a while back on the bag and it gave me the idea to try it with my Ferd Ranger that is getting tired and is gonna need a new heart. The sad part is that is cheaper to find and rebuild a slant than it is to do the same with the stock 4 banger. And I'll get about the same mileage... :wack:
