[bigblockpolara]

I have a 72 bigblock Road Runner with an 8.75, 3.23 single spin rear. I have a 9.25, 3.55 sure grip out of a 1978 Dodge Magnum......question is will this swap work w/o alot of mods? I purchased this rear end very reasonable and would like to make it work....thanx guys!:confused5:

are you looking to get better fuel mileage or performance?
