Would you please list the junk clutches that destroy drive train parts so we can avoid them?
I have run McCloud and Centerforce street and strip set ups in my cars and have had no problems with 18 spline and 23 spline transmissions (stock).
I did however, wreck a pinion bearing in my 440 23 spline 4 speed '69 Super Bee with some hard launches and sticky tires. A Dana 60 resolved that, like it should have.
I have had some bad luck with stock clutches slipping, but no drive train failures.
Thanks,
Tom.
