Underdrive Pulleys

[91LTDProject]

When you change that crank pulley, is the size decreased so much that you can no longer use the stock belts? Or is there enough play left over to adjust the extra slack outta the belts?

nope...only crank. No other pullies are available.

Did you change your water pump pully?

Nothing is interchangable. ASP does make that crank pulley. That's it. Works great though.

Is there a underdrive pulley kit available for these cars? All I can find is kits for the mustangs, which are a single belt set-up. If theres none directly made for our cars, is there another kit that would be interchangeable?
