when the time comes to replace or rebuild, im either thinking of keeping the 8 valve and rebuilding it for more power, or im tossing the idea of figuring out how to sink a 60 degree 2.8,3.1, or maybe even a 3.8 out of a gm rear drive applictation. i figure it will up the power with adding extensive weight and still be reliable. but i gotta say this little thing suprised me with all those miles it blazed through mud and deep ruts, with bald street tires with no lift yet like it was nothin, well the exhaust was broken off but thats it. before this weekend i was lookin at jeeps but now that i have first hand seen the potentiol and aint skeptic of its capalbility i will be keeping this mini rig for as long as it holds up.
