Also, I wouldn't be surprised if this is either a manufacturing defect by Scat or Clevite. I doubt Butler would even check something like this on their own builds,

This cannot be a normal thing, otherwise garage hobbyists are doomed. If a hobbyist needs to go to this level of inspection detail on semi-finished parts, it becomes an unworkable project for most of us.

Moving forward, I would caution anyone against purchasing their own parts and doing this. Let your machinist prepping your block purchase the parts and have responsibility for them.

Unfortunately, there are No guarantees no matter how you play it....

Just because a builder supplies the parts, builds it and you blow it up a day later later doesn’t guarantee squat. Too many variables.

I like to run em on the Dyno before install. Much easer to repair a problem found on the dyno. At least I have a chance at knowing it Might hold together AFTER I install it.

How long it will run after install is still a crap shoot on even a moderately built Pontiac. I drive em hard....
