help with engine position and 671 supercharger
 

I am just working on my chassis and could do with some information please.
i have a c10 small block chassis/frame. and i am fitting a 671 supercharger. I can not measure the engine against the cab, as that is in the shop and miles away from home. i am trying to work out if the small block with the blower pulley will miss the front cross member.

or will the supercharger work with the I6 engine mounts? will it touch bulkhread. what has anyone else done?
