Also one more think to look at, check the oil level and male sure it does not have to much oil in it. I know it sounds stupid be humans do forget sometimes.

The dyno break in should be fine. Joe has been doing this for 50years but He doesn't believe this crankcase ventilation is a big deal. Not sure why!

We ran the 7 qt pan with 6 quarts because the windage won't work with the big stroker crank.
