Muncie M-20/21 or T10 users?

a super t-10 should not even be compared to an 833 and the muncies are junk. there is a reason in super stock and pro stock before there were clutchless tranny's every manufacturer used the 833. no ford top loaders, no muncies and no t-10 junk. now if you want compare how well they all shift for normal street driving then yes the t-10 is on par with the 833. thats it though they are junk otherwise. i run a stock 23 spline 833 behind a 416 that make 550 hp in a 3700 pound 70 challenger. i've broken a main shaft in 16 years. no gears breaking no cases cracking. never seen a muncie or t-10 last a season !
