Late may 2008, California speedway: Track elevation of about 1300ft, about 70-80 degrees, curb weight of about 2600, very old 185/70/14 tires, stock 3.55 open R200, FAST 78mm intake manifold, pretty big cam, LS6 heads, dual 3" exhaust to open cutouts, T-56, 420rwhp.
12.351@120.06 with a 2.069 60ft was one of my better runs, 1st and 2nd gears were pretty worthless. 3rd would hold if I got into it at only about 3k rpms
