318 dyno run.

It wasn't cheap to break it in on the dyno! $800

But there was good reason for it. The machine shop ran the bolt into #1 cylinder, first thing I checked when I got the engine back. It wasn't much,but enough to be a concern. Getting a flat tappet cam to break in properly is super important.
Since the carb took a ****, it would of been difficult to get the cam to break in correctly with all the trouble shooting in the beginning. Glad I did what I did.

Didn't want to get it all in the car and have to yard it all back out because something went wrong. Plus, new ceramic coated Doug's headers are not recommended for break in.

Maybe I'm making more of the cam break in than I need to, but that was very important to me.
