I have a 91 Rodeo 4x4 with a V6, standard transmission. All stock. I would like to either put a Toyota V6(3.4L), A Chevrolet V6(4.3L) or a Chevrolet V8(350). Anybody know if this is possible without having to modify a whole bunch of stuff. I know the motor mounts will most likely have to be modified which isn't a problem. I just don't want to get into cutting up the firewall and stuff like that.
