Ford Rear End???

[wildmanracer3]

I am building a new 4 cylinder and when I bought the car to start on the cage it has a 8.8 5 lug in it. What are you guys running? 7.5, 8 or 8.5 Is there any advantage or disadvantage to any of them and what would I need to covert this to 4 lug if this is the best one to have?
Thanks

if possible id find a 6 3/4 from a 1979 mustang..it is 4 lug and a direct swap,very lightweight.

The lightest weight possible they are all strong enough to hold up to what these motors put out. Its all about getting the rotating weight off.

i prefer the 8inch in a mustang. you can make your mounts so that you have an advantage over the 6.75, 7.5, and 8.8. all are strong but i have seen axles break on the 6.75 on rough tracks.
