Tweeti dont drive my mustang too often because it needs alot of work i have had it since highschool (i graduated in 87) i drove it today to work after finally getting its new tags and inspected after 2 years of never leaving my neighborhood. i let her warm up and nailed it. now i have a knocking sound in my baby. sounds like a rod. the motor has about 50,000 hard miles on it and hundreds of pounds of juice run through it. i dont have the money to rebuild it now so i guess it will set again. poor baby anybody got a spare 351 c?
