Davis, yeah, but what you didn't know is that I am fortunate enough to have 2 engines #1 588 ci #2 516 ci running everything the same except shortblocks. also, I never said I was going to use anyone else's tuneup.... just that I was curious where everyone else was at. The 588 ci. (4.500x4.560)has been run all season, as often as possible, and being freshened up. The 516 ci (4.00x4.530)is the backup. I'm running for points. I don't know how to do a avatar but if you care to see my car its on umtrdragrace.com in photo galleryunder a couple different dates, its the wild purple 65 malibu.
