OK I need some help on a engine swap for my jeep yj, its a 89 and I will want to be able to drive it on the road. My qusetion as I am not to familiar with Utah smog laws is what can I get away with? small block Chevy or will it have to be Mopar from the same year or newer? I thought about a 4.0 swap but you know more is better. let me know and if anyone out there has some parts let me know also .
thanks
