I had a 307 in a 69 nova years ago.I think it was a stock engine,it had a power gliude behind it,didnt run to bad.I just found me a 71 nova,307,th350,been in the same family sence new.71000 original miles,ac car,I really like that.Point is I dont want a drag car but would like a decent running street car.I've always built 327-350's,not to hard to get decent HP out of them.What can I do to this 307 fairly cheap to make it run and hold together?
