Ford flathead model 60 motorcycle/chopper

I have been doing some crazy thinking and was thinking about a chopper style frame and chassis using the ford flathead model 60 as a power plant. I have seen the pictures of the "honest charlies" flathead powered bike but it looks too honda-ish like a goldwing or the aspencade for my liking..

Is the 60hp block physically smaller than the 100 hp block, why not use the 100? would look cool w/ 3 deuce's and Fenton headers.
