engine

I know this is probably a stupid idea, but would a 2.0 ngine be a direct bolt in for a b2200? i think my motor is pretty much shot. i found a rebuilt long block 2.0 for 650, and he damn 2.2 is 1250. I aint trying to race my truck or nothign, I just wanna be able to ride low as hell, and cruise. I aint trying to win no drag race or nothing. How hard or easy is it to replace the 2.2 with a 2.0?
