There are a lot of racers that say since synthics have emerged that rule dosn't apply anymore. Don't care, the 10 per 1000 rule has save my wallet.

Jeff,
I was aware of the rule. I did not expect this motor to wind up with such ease. I figured it would be done by 5500-6000 rpms. We were just running regular 10-30W oil, no synthetic's. I think a high pressure pump is one of the change's we will definately make.
I am considering a higher strength rod than the Probes we had last time also.
What are you doing for your next motor?
This post is getting way long, and I still need some insite on other damaged engine parts that happened when we lost our motor so I think I will start a new post on those subjects.
Thanks for all of your help,
Gregg
