why don't you buy a used engine for about $2K and then use the remaining money to rebuild it and do a few internal mods like strong bolts, etc. You'd end up about the same ballpark price and you'd get more for your money. With all the problems popping up with ATK engines lately that is a scarey thought.
Just my .02 cents.
