Well, another set back on our quest for 10's. We did a little tranny work and put it back in the Silverado SS.
Went out and stalled it up to 7psi and POP, broke the output shaft in half.
I think we are making a little power :smile: Now its time for the customer to spend $570 on a hardened shaft. We are giving the 4l65 one more shot before upgrading to the 4l80.
