Hi all. I'm new to this site so just getting used to it. Hopefully I'm doing this correctly. Anyway, I have a 79 malibu that I have put a 325hp 454 in. The rearend in it now is the base line 2.29 7.5 ring made for the v6. I know that I am going to break this in no time. I need anyone's suggestions on the best rear end for my application. This car is really a show car (I'm in upstate NY and this car is from AZ with less than 110k on it and in prestine condition), so I am looking for something I can just bolt in without any mods. Now that being said, I am quite sure this car will end up seeing the strip more than a few times, so I am looking for a dependable rearend with posi that is great daily driving, but also can handle a launch at the strip. I was told by a guy I should invest in a 9" with third member so I can interchange gears? Any suggestions would be greatly appreciated! Thanks!
