do 340 rods wear out?

The new rods do not have oil squirt holes. I like squirt holes.

I agree. i like the idea of having the extra oil lubing the wrist pins and cooling the pistons. I wish the new rods came with oil squirt holes.

I just paid $150 to have my 340 rods resized on the big end, and install new bushings. Plus I bought new arp wave locks at $80. If I had to do it again I think I would just buy a set of scat rods.
