WEll got her dialed in ,in just 2 trips to the track 71,with a 355 ,patriot heads, 294/306 comp cams, 410 gears with 28" tall tires ,all street trim,the first time i went i have a regular fan with no cut outs and went a best 12.30 at a pinks all out here in louisiana,so i put an electric fan,and cut outs and drove 50 miles to the track and went 11.75 @114 mph so that was a big difference and even has power steering
