Wow! Our rod bolts lived but the big end broke of like yours.

The Nascar boys run the RPMs way up. Our motor pulled like nothing I have been around, I think we got very lucky on the combination and
you had way better rods than my son and I, and we were bouncing this thing off the 7000 rpm chip with ease. No valve float, no problem.

I wonder now....do we need ultra high buck rods?
