I have to ask what you have in your 97 Cobra? Its just a curiosity thing.. Oh and couple more things.. i pound my car hard and with 11k miles i use zero oil.. and its true that the cars make more HP after breaking in (what kind of dope races a brand new car?) .. with $200 in mods i dynoed at 320rwhp (~370at crank) and 333rwtq.. So i wouldnt go knockin GM too much..
long live the blue oval / bow tie battle!
