I've heard horror stories about belts slipping off when putting underdrive pulleys. Is this true? I do a lot of traveling in my stang and don't want to be caught stranded in the middle of nowhere just for adding a few horses. Please share some experiences.
Just follow the directions and torque procedures. MAKE SURE you put some RTV in the crankshaft keyway,don't tighten the install bolt(Steeda) to tight and you'll be all set.
