I recently read of someone specificly using a '42-'48 cam as they said it was the best stock cam for low/mid range torque.

Did the cam profiles change over the years and are some years better than others?

JW Lawson did a lot of dino work on flathead cams his results are in his book,simple answer is yes stock cam is better for low and mid range torque.

The 52 EAB and EAC changed timing to improve performance in the 2000-3000 RPM range, but personaly I don't think changing cams is worth the cost and effort and you'd probably get more usuable torque by milling the heads.

Have always heard 'stories' that one year or model Flathead had a better cam than others right out of the factory. Is there a chart printed somewhere, maybe in one of the Ford Flathead books, that compares the differences between stock cams from 1932 to 1953? I'm not that interested in comparing a bunch of dyno tests with engines that may have other variables, would just want to understand the dimensional, angular, lift and core material specifications for all the stock FH cams. Can anyone lead me to this kind of information?
