Re: What rearend?
The Ford 9" would definatly be a beef up! It has been my experience that the 8.8 is very durable though. I have been running it in my mustang for many years at the drag strip and never had problems. A 8.8 with a fresh set of parts and gears will last at least 100,000 miles it not sevierly abused and maintained properly. But if you want a 9", it will never break with 33's and a stock motor. It depends on how serious you are going. 3.55's will be ok for 33's, I am running 3.55 with 35's and it isn't too bad.
