Dyno day two. George Widuch is on the way to help work the engine. We make two pulls on engine to establish todays base line. Time to change the cam. We degree the cam in using our notes and our ATI damper. Using the damper and cover works well if it is checked for TDC when you have the head off and using a larger degree to establish true TDC. I checked the centerline numbers after the dyno session during disassembly and was only off a 1/2 degree.

The second cam moved the numbers up about 200 on the rpm scale, and the engine seemed to like the change.

Time to get ready to make first hit at 2013 Indy. Man am I uneasy about making the "Show"
