Turbo cam question

I suggest anyone interested in the subject pick up a copy of the HOT ROD article in question.. prob in the HR archieves. Aw, hell I'm in agood mood..here ya go now read and read again .. then when you think you understand.. readit one more time.. not trying to a smarty pants.. just want you to understand.. Note cam info, later turbo design info etc etc.. A 115 on an old to3 or to4b is NOT the same as a BB whatever.. good luck! A little infomation quoted incorrectly is bad info..
