massive reconfiguration time again.

I'm starting to remember why I bought that $50 318 and rebuilt that automatic transmission last year? Freaking oil change on this motor cost more!
Again in order to start affording to drive this car a little more I'm going to have to start using some common oil with a zinc additive. It has 30 weight Penn grade break in oil now and always has run 15-40 Penn grade. also I want to start experimenting with a little bit lower octane fuel. I'm not sure what the cam will allow me to do, but it sure doesn't ping at any RPM in any gear it seems like. Of course that's running 100ll right now. I want to get a couple gallons of 92 non ethanol and see what happens.
