nate, i wouldnt use that link you put up, sounds lie "joe bob's shade tree builder" with a internet connection
you can get a complete long block from Napa cheaper than what he wants, i think they still use ATK engines
It would be cheaper to buy a used engine and do a power rebuild yourself buying parts from Engine Builder. Check craigslist in and around your area, you should be able to pick up a used engine needing a rebuild for under $200. If you can swap an engine, you should be able to rebuild the 22r yourself and have a nice performance rebuild w/header and carb for under $2k.
did you see Jimbo's motor that he thought he could do just because others have??
