Hey guys I am looking at buying a 97 6 cyl body with a 351 windsor motor that is bored 30 over, w 305 cams and springs, an edelbrock intake mani, shorty headers, SINGLE flowmaster exhaust, and 20" wheels. Now I know roughly what this should put down, and went on a test drive today. It seemed very slow for a 351 windsor. I spun all of first, only spun a little in second and no spinning in third, and it had bald tired. The idle is nice and smooth, its not leaking, smoking, overheating etc. Do you think a single exhaust, and 20" chrome wheels will make the much difference? I don't want to buy it and be disappointed. I tested the car yesterday and looking at making a decision today, Thanks for any fast help!
