I didn't have any intention of using this idea for rock crawling. I just thought that it would be a cool idea to put that type of engine in a light (or even a heavy car) car, and make a fun muscle car. Put it in a 2 door Jeep Cherokee Classic. Get rid of the 4wd, and make it a solid live axel in the rear. Drop it down lower to give it a more car like look and feeling, ditch the rear seats. Maybe even cut the top and make a new roof with a fast back or trunk. I just think the Jeep Cherokee Classic front end would be a gorgeous front end for a muscle car. Almost Cuda' like. I'm a welder, so its not out my realm of possibility. Just picture it.
I have an 87 Shelby Charger, and I need to put a new floor in it. I figure, if I'm going to do that, why not put a trans. tunnel in it, and make it rwd? I think an inline 6 would fit a lot easier than a small v8.
