It's a 72.....and you will keep it forever......

IMO, keep a small block in it

So, put a 4" crank in it, have the heads done by IMM, have him spec u a cam, get a good converter, put a clutch suregrip in, some sticky street tires, frame connectors and maybe a 6 point bar and have fun without a lot of coin.......should be able to do that for 7k or less and still have a low 11/hi 10 car you can live with on the street....
