well, its a standard small block chevy, so any small block chevy, baring an SB2, LT1, LT4, LT5, LS1, or LS6, will bolt right in. so just go hit up SDPC2000.com, or any authorized GM performance parts dealer and page through the available crate engines, that or any other aftermarket offering for small block crate engines. as far as what to do to yours, depends alot on how crazy you want to go. i mean, how much power to lookin to pump out of this thing. realisticly that is. and how much you looking to spend, also realisticly.
