suitable small block home?

My buddy is gonna be cleaning out his farm and has a 2 door Chevette that is sitting on his property he may let slide for extremely cheap. Cheap enough that I am even considering buying a Chevette. Would this be hard to cram a small block in? All im gonna do is romp the damn car into the ground with a junkyard small block. I am honestly curious. Im not a huge fan of these cars or how fugly they are, but they are really light.
