Let's see, I got my S/C around '04 and I think from just previous to then, all S/C kits came vanilla with the 5psi pulley (IIRC). I know mine did. Perhaps Tone can shed more light on this if you PM or email him, depending on when you purchased yours.
Not so sure what the stink is concerning the difference between 55hp and 64hp. Seriously, do you really think you are gonna feel the difference there, hahaha.![]()
