They also had retarded timing, with a very slow advance curve, and leaned out carb with #68 primary jets. With headers, jetting and a good advance curve, it was pretty easy to knock more than a half second off the quarter mile times. Those who just bought the cars and drove them could never quite figure out why some cars were so much quicker than theirs. The answer was actually simple enough that I even had it most ways figured out.
