LS powered Duster, Abomination or Go For it!

Your car, do it your way! :thumbsup:
This is such a safe and neutered way to respond.
That just isn't my style.
The OP asked for opinions. Here is mine. Get ready.
GM engine swaps are bullshit. If Ma Mopar built shitty engines, I'd understand. If this were Cuba and no viable Mopar engines were available, I'd understand.
Neither of those apply here.
Yeah, it is HIS car and we have no right to expect him to abide by our suggestions but.....He asked for it.
The LA and Magnum series engines fit with ease. They can make great power and are quite reliable. No need for aftermarket wiring harnesses, fuel system overhauls or calling in experts to tune the thing.
Simple facts.....I don't like Chevy engines in Mopars. I don't like the aftermarket coil over suspension stuff either. I am fine with off brand transmissions and aftermarket brakes though.
