I wouldn't hit a dog in the butt with a chevy motor. The best V-8's ever made came from the 60's and 70's, out dated my butt. All V-8's take the same speed parts to mod them, chevy isn't special. Cam, 4 barrel, intake and headers. All electronics were weak in them days and still got the job done. Were not talking stereo's, were talking jeeps. You can cut up your dash all u want, it's yours, just saying I don't. We have taken stock jeeps over the years in places where you couldn't drag a chain. If your a non operator, you would need a rubicon to enjoy your jeep off road. A rubicon is just parts, you can put them on your self, or pay the factory to do it. Where do you think jeep got the idea for the rubicon, from seeing what jeepers do to their jeeps. The 258 isn't weak, when it came out it had 150 hp and 240 pounds of torque, not bad for early 70's. It was the emissions equipment that left the 258 struggling to breath. My 258 doesn't have that problem. I installed a 470 holley 4 barrel, offy intake, rollor rockers, ported head, comp cam, header, HEI and MSD. It breaths way north of 200 hp with gobs of low end torque, I don't need a V-8. The AMC 20 is hardly weak, it just needs one piece axles and it's very strong. When jeep put yj's and cj's together, they were intended for 40" tires, or to try and climb boulders, it's called extreme for a reason. Have never had a problem from a D-30, most of us don't, that why we still have one. I knew some one like you would be a long to bash me for having a passion for jeeps and what they stand for. I'm a jeep purist, but not a prude, I love modding my jeeps. I just think we should leave enough of it so that it still is a jeep, that what we wanted when we purchased a jeep, a jeep. Not a blazer, GMC, or military duce and a half, but a jeep. That's all I'm saying and that's just my opinion, not law of the land. So chill the frick out !!!
