Thats the thing...
neither you or I, without blowing something up or trying our darndest to do so, can prove wether the seasoned better steel of the 60's/70's is better or worse than the chinese more meat in specific locations rods.

I have seen them both break.

history behind used sets bought at swaps is a mystery.
american faith is fair weather when it comes to chinese made steel/stuff.

Whats interesting...is that when it comes to chinese rods, all are sold that they are better...
BUT....when it comes to rocker arms.....get out the holy water and start praying...ha ha ....nothing but fear from most.

It's almost comical! :tongue1:

I would ask what brand have you seen break?,I have run cat h-beams (about the cheapest rod out there on e-bay) in a ton of engines with no issues,alot of high end pontiacs run them,just have them honed and they are good to go.I have only heard of failures with eagle I beams where scats etc. seem to have a good rep,I have never ran an I-beam personally but have built a few successful engines with them.I will say there is not an h-beam on the market that would break in his engine.
