Ive done simple hone,re-ring,bearings, valve job and a good cam on low comp mopars and pont. big blocks and even ran a 150 shot on them from time to time and they lasted 40-60k of fun hard street bashing way back in the 80-s and would even beat a improperly built car from time to time.

What was the good stocker vert, the "J".

They were strong enough to break fresh trannys and rear diffs and the worst I ever did it break a oem timing chain.

I think alot forget what we used to do and had a heck of a good time doing it.
