LS powered Duster, Abomination or Go For it!

Custom exhaust, mounts, headers, computer and wiring, etc stuff adds up quick. Sell the 5.3, buy a small block mopar, and save some money and a lot of aggravation. Just my two cents.
I agree, sale or trade for a small block Mopar. It's yours, do as you please, but having a motor of a different brand in another body may cost more than you think to install. Fabricating linkage and mounts along with a custom drive shaft, is costly. Myself, if I see a nice or cool GM, Ford or Mopar I will stop and admire, but if it has a different drive train then the brand, I will move on. That's just me.
