i have a 54/3100/235 upgraded with fenton headers dual exhaust and dual carbs and t-5 trans 2.73 rearend and cruises at 65-70 under 2000 rpm. the only thing i would change is to auto trans if i lived in a big city with traffic. i was caught in a traffic jam in indianapolis and my thigh muscles were very sore the next day, btw i am 65. the issue is my son refuses to drive a stick shift and i assume he will inherit it as he is an only son. ron
