Need Advice on Low(er) Budget Race Build

Got a 66 Valiant Signet coupe. 1968, I wasn't saying I was going to buy the whole dang thing now. I was trying to get an idea what kind of start I could get with a $2k budget for the time being. I'm trying to get ideas as to what routes people are going and what kind of results they are getting out of it. I'm not asking for a way to spend $2k on an engine and be out racing 9s in 2 weeks, just what people are doin, how it turned out, and what's the least expensive way to get semi-acceptable results.
