Well, hopefully you can keep us posted on your results. I havn't done such a good job at that with the buisy dyno thrash and a house guest for the past ten days. Didn't make for much computer time.

Les, it was a plesasure meeting you as well. Thank you for coming by and hanging out with us.


So, the engine still sits on the cradle right where I unloaded it last Thursday. It's been go go go with everything around here, and getting back to work after a week off.
My only issue with the engine was that the oil pressure was falling off between 6000-7000 rpm. It did the same thing every pull. The pressure would climb very smoothly as the RPM was increasing, and then gradually fall off from 70 down to around 50psi at the end of the pull. It did the same thing pull after pull with the oil level enywhere from six to eight quarts in the pan.
I think that with the external oil pressure regulator dumping all if the excess oil back to the side of the pan, I created a bit of a flow restriction on the pick up tube side. We discussed that months back as well as the possibility of cavitation, and I am now going to build a larger pick up tube to see if that helps the matter.
It may be another week or two to get the engine back in the car to see how it works.

Here is a quick video of one of the pulls last Wednesday.
