Big block cooling question

IMTERESTING:
I JUST YESTERDAY , BLUEPRINTED MY ALUM. HOUSING, WHILE I HAD IT OFF TO MACHINE IT shorter , TO ACCOUNT FOR THE MOTOR PLATE. Had to machine the alternator spacers off the same amount. All I had to do to the crank pulley was to remove the spacer that I made back when I put the engine in. I still don't expect much clearance from the new fan clutch and the radiator. This will be the last experiment w/ fans, will use the one that works "worked" best.
Still would like to overdrive the fan a little tho--------------
