To Resize Connecting Rods or Not?

I only made it to the angel/devil point but in my opinion it’s not the clamping load that distorts the rod. It’s the criminal press fit of the bolts.

The first time I used the much loved and worshipped ARP wave lock bolts I was stunned by the amount of press fit that bolt had.

Being the prick I am, I called ARP and was told that’s what makes the bolts better. The extra press fit makes the rod/cap interface stronger.

I didn’t buy that so I called a couple of engineer guys I know and they didn’t buy that either.

If the bolts you are replacing have more or less press fit the rod will distort.

I sized every rod that came through the shop. It wasn’t an option.
