it's insane, the shorty pump is readily available and the pulleys are not. unless you don't mind getting gouged. i pulled out my old (4/28/06) receipt from summit: the pulley set was $144.88, of course I had to buy a water pump @ $129.95 and my application required a crank pulley spacer @ $25.88. even then this was a lot of money just for a little extra clearance.
another option would be a remote mounted inline electric water pump.
or maybe you could talk 5 other people into a group buy, much cheaper:

i've got a brand new cover, pump, pulley and fasteners i pulled off crate motor i'll dig out and donate to tffn after the holidays.
