That chart was great I just ordered a 3:55 and was hoping i made the right choice. According to this chart i did I put several hundred miles a week on my car at 75+ anymore would have been to much.
Was wondering if anyone could tell me what is special bout my engine. I have been told several things such as 1.7 roller rockers,bigger throttle body,GT 40 heads. But im not sure. Its all stock as far as I know. Thanks for any help.
