Q...I am still up in the air with between 3.23, 3.36, or 3.55. This Firebird I just bought will be my daily driver as it is my only car and feel comfortable with it probably breaking down from time to time since I live so close to my studio...so, engine wear is a slight concern of mine. Although I totally understand how individuals would want to baby their cars (especially after searching for so long for mine, or perhaps having a different car as a daily driver), I believe in the saying "drive it like you stole it." haha, also, "old enough to know better, too young to care!" Anyways, do you think that 3.55 and a regular highway a$$ hauling will wear that much on a 350, or even a 400?
