I was just kidding about the 632 it is overkill for a street car but all kidding aside my buddy has a 69' Nova with a pump gas 598 BBC pushing close to 900 horse and what makes his car streetable is he has a Gear Venders over/under drive and he comes down here on the freeway about 40 miles just to go to car shows with me around here, something you might consider for your Nova at some point and maybe you will enjoy it more.
