mismatched pullies, will it work?
 

Ok, so i have a steeda water pump pulley already, got it given to me, now i want to go buy the "asp" crank pulley, think this will be alright? i may already have an underdriven alt pulley, being its a ex highway patrol, either way im gonna skip the alt pulley, what you think?

It will work okay no matter what size pulley you are running on the alt. All you will have to do is measure around the pulleys and make sure to leave abit of leaway for the tensioner. That will be what size belt you need. I am running the racing crank pulley, stock waterpump pulley and underdrive alt pulley.

Ya, those pulleys will work fine. when i put on my pulleys, i was able to re-use my stock size belt.
