One must remeber in the day (1957) Ford had 2 sets of pulleys one set for Stick and one for set for auto.

The reason I mention all that is, at the time, I asked about changing the pulley diameter. I was told that only the STOCK pulley diameter would be allowed. Rules for Supercharged Stockers aren't addressed in the rulebook, but back in the old '57 Ford days they had to use the STOCK pulleys. Hardly anything else has changed in Stock since then, so I was just wonderin'.
