im selling a 77 chevy nova with right around 80,000 miles the car has a 305 with a holly 4 barrel and a k&n filter its an auto the car runs fine the only thing wrong with it is it has an oil leak witch isnt a big deal because a 350 swap would be ideal and also the car wont shift on its own till like 35mph someone told me it was a modulator valve but i am not sure here are some pics
