"Breaking in Big Block"

For the last 10 years or so, I've been running Jomar 100% No Bypass oil filters on my hotrods. It saved one of my motors from oil passage contamination when I lost some rocker arm needle bearings due to valve train harmonics taking them out.

Another thing I've been doing on fresh engines for a while now is installing a section of screen in the top radiator inlet before running the motor for the first time. It's just a 5 inch square of screen that I shape into a sock type shape, insert it into the radiator nose bung, and wrap the edges over the outside of it. I then slip the hose over that. It's amazing how much stuff it catches from the inside of the block's water passages. I remove it shortly after it stops catching stuff that would otherwise end up inside the top radiator tank blocking the tubes.

Kindly overlook the current wiring mess, that's my last step before it's running again.
