what's wrong with the 7.5 malibu rear?
I have read a lot of bad things about the stock rear of my 81 malibu lately (converted to el camino by myself ) the truth is I didn't pay any attention to it until now, it hasn't braked anything yet ( I hope it won't ) it lives behind a 350 with a 144 B&M supercharger and it's hotter cam, 600 cfm holley, headers, etc. do you think I should worry about it? I have a 1977 malibu rear end sitting in my shop, I'm not sure about the size but it's the one with the squared ears at the bottom of the pumpink, is this a better choice? should I replace it? I don't race the car, it's a street tire fryer only.
