Most 77 and 78 novas had 6 cylinders and automatics in them. Less than 1/3 have v-8s. That sounds like a pretty reasonable price. Hopefully the title is nice an clean. Also the big thing to be aware of is since they have the front subframe, you have to make sure all the mounting points are in decent shape. You may have to buy all new mounts and have your subframe realigned as it will affect your driving in a straight line. Don't go too crazy engine wise unless you get frame stiffeners and tie-ins for that subframe. They were neat cars though. Just remember the limitations with the subframes.
