Need Advice on Low(er) Budget Race Build

I have found a few C body 440 blocks around town but they've been garbage. Seems like the only ones I've run into are numbers matching with the car and the guy selling it didn't want to separate the motor from the car (understandbly). Drags are in town this weekend and I actually just came from there and was talking to a few of the guys that were runnin Demons and Dusters with 340s and they were runnin some good numbers. They said that parts could get costly runnin sb though. Keep them ideas comin!!!
