    I just finished rebuilding my flathead last week. it has a stock ford crank and mercury heads. my question is should i had installed a 4" mercury crank? or will it be ok the way that it is?

    The Merc crank would give your flattie slightly higher compression ratio, and with the 16 cubes more would add up to 10 or 20 more horses, but it'll run fine as is. You don't run a flathead for the awesome power anyway! It's all in the look and the sound!
