i have a 90 thundbird sc that has 90,000 miles on it. it also has a full flowmast exhaust and air silencer removed with k&n filter. i was thinking of putting a 5% pully on it, would i be putting alot of stress on the head gasket? if so, any hints as to how i can squeeze out a few extra pony's anywhere else?
