My 70 model Nova came with a 307 2bbl three speed standard. It had 17,000 miles on it when I got it. I installed a Tarantula intake Holley 1850 carb, Crower hydraulic camshaft and rev kit, Cyclone headers, Mallory dual point and a Muncie four speed. Car would run 13.50 quarter miles times all day long. Drove it back and forth every two weeks from Beaumont Texas to Abilene Texas for over a year with weekly trips to the Abilene drag strip. I wish I still had it.
