Thinking of putting a fabbed rear in my 79 malibu. It's a bigblock put out 680 on the engine dyno and i will be running a 400 trans(not 100% on the trans yet) I'm guessing the car will put around mid 500's to the wheels. i'm set on one of these to rear end's and looking for input form anybody that has either of them, like fitment issue's etc. Car will be mostly run on the street, Only race track time will be mostly friday night test and tune's. I'm guessing alot of people will recommend the TRZ, but i'm thinking it may be overkill for me.
