I talked to Bob Langdon of Stovebolt Engine Co. last night. He says he has a good supply of lifters on hand. He also sells a cam that he likes, it's a dual grind with the exhaust a little longer duration than the intake. Anyone try this cam? He says idle is not as smooth as as the M4F cam but he has done some dyno work to develop it. He will be in today but is taking the rest of the week off to go to swap meets. He also has a supply of the powerglide intake valves for anyone who might want to put in bigger valves.
