about a year ago i got a 1990 SHO with only 63K miles. this car was all orignal, it still had its stock clutch even its in almost perfect condition for its age. its been a great car for me. i put flowmaster exhuast on and centerforce clutch on it. i need some questions to be answered for me. it now has 78K and runs great but i know it needs matience, can anyone tell me what i need to do to make it run even better remember.....its all orignal nothing has been replaced, and also im looking for some 1991 slicers for around $150
