Yep those were the S_ _t back in the day.
We used them in Ford 460 I think they came out to over 500 with those if I remember right. It's been along time ago. we also used them in Dodge 440's and I think the 400's as well. The 400's have more material in the blocks then the 440's did.
I don't remember all the details weather it was shaving the rods or crank and that stuff
I just remember using the rods in alot of other big blocks with a few mods done to them.
