Keith used .003 on the mains. Not sure about the rod side clearances. Tony was strongly encouraging me to go to the heavier Joe Gibbs
oil. It is 15W-50 instead of 20. That was my faulty memory. Since I've moved the idle up to around 900 my hot pressure at idle holds around 20 psi with the lighter
oil so I'm thinking either is probably fine. Yes, he did break it in on the dyno but I would like to get a few more miles on it and get accustomed to the car.
I'm pretty pleased with the Spin Tek low profile mufflers. I was afraid they would sound like Flowmasters which are not a favorite of mine. But they sound better in my opinion. At just 3 inches thick they are a good choice for an undercar exhaust system on these cars. Thanks for the feedback.
