Spare package arrived from a friend doing an LS swap. Every engine sensor, OCV, and Fensport underdrive water pump and alternator pulleys. Got a longer belt on the way. These pulleys will slow down the water pump which tends to cavitate, and the alternator which doesn't need to spin so fast to produce the needed amps at sustained high RPM on track. Will also theoretically pick up a couple HP but that's not the point.
