How dificult, on a scale of 1 to 10, would it be to rebuild a '94 Jeep 4.0L I6? I'm considering purchasing the parts to stroke the motor. There is a 4.7L stroker kit for the 4.0L motor I can get for around $1k, and have one heck of a motor when I'm done. I'm fairly handy with tools, but I've never rebuilt a motor. In the last two weeks I've done smaller things like replacing rotors and pads, changing spark plugs, checking compression, changing fuel filter, draining/flushing (via the aux cooler return) tranny fluid and replacing filter, drain and fill differentials, drain and fill transfer case, changing oil, replacing throttle body with 62mm bore TB, etc. I plan on installing a lift and replacing shocks next weekend. I've done all of this by myself. I guess what I'm asking is, do you have to be somewhat handy with tools and know how to read and follow directions (which I can handle), or do you need to have in-depth knowledge of the inner workings of a motor (i.e. be a mechanic, which I'm not! )? I have a basic understanding of how a motor works, but I've never torn one down before. What do y'all think? I know it'll take me a couple weeks to complete, and there are several things that will have to be done at a machine shop (boring cylinders, etc.).
