I plan to use my 66 barracuda at the track. I am looking at a ford 9 inch for the back. I have a 440/ 500hp, and a 727 tranny. Can anyone help me figure out the flange to flange width of the ford and what tire size I will need. 51.4 is the normal f to f on a a-body 8.75, right? But to make room for slicks, Im not sure how to figure out a close starting point. I guess at this point I could use a little experienced assistance. I will tub it natch. Thanks. I have a chance to snatch a 52" f to f on ebay If I hear back from somebody within the hour, thanks much guys.
 
Whenever you're putting big tires, tubbing, and narrowing a rear, the first thing you do is buy the wheel/tire package you want. Then you measure to determine how wide of a rearend you need. Obviously, you'll have to do the tubbing and moving in of the springs first. Trying to narrow the rear first and then buying wheels and tires can be enough to drive a man to drink. Do it the right way if you're gonna do it.
