As we all know from forums, this great nation is littered with the remains of thousands of grenaded 8” rear axles who gave their life to provide their owners motivation to swap to a 9” when they accidentally put a 2 barrel on their 200 Inline 6 and overpowered the teeny axle. Everyone would love to have the brawny 9” under their car with gleaming 31 spline axles, but let’s face it. Is it truly needed? I’d like to discuss the merits of keeping the 8”. What are the real weak points of them and where and when do they fail? I bring this up as someone who use to slap M/T ET Streets on my daily driver ‘66 with a stroked small block and hammer on it at the track. My 8” never failed me and never showed signs of premature failure. I’m currently building my ‘66 coupe into a street/track car to toss around the track on weekends. I’m planning to push around 400 at the crank and run a Detroit true trac. I won’t be shocked if I have to pick my 8” up off the track at some point, but for now I’m on the verge of ordering a new nodular center section and heavy duty pinion support to try and beef up the 8” under the car currently. What are your thoughts and experiences? If you’ve had an 8” give up the ghost, what were the circumstances and what actually failed?
