greetings all,,i have a 02 blazer zr2 with a 2" suspension lift,,
just purchased and 450 hp 5.7/350 engine,,,which i will b putting in this week..
so my question is,,I was told the zr2 rear-end cant handle that kinda power,,is that true,,,if so does anyone have an idea which rear-end i should put in,,,someone was saying an Dana 44 might work,,,

kinda a newbie 2 this mechanical stuff so thanks 4 ur help

 

the zr2 has the 8.5" ring gear. dana 44 has the 8.5" ring gear. basically the same thing.


i would think it might hold up fine depending on how wide of tires you run. ive known people to run 10 second cars using stock 10 bolt axles in camaros

 

Cool thanks,, I will b running
31x 10.5 MT tires
