Speed inc. 427. Dyno numbers!! Dynoed last week. Made a few changes. Specs in sig. This is with a nitrous cam, HD drive shaft, 12 bolt, 33 spline axles, dynoed with the slicks on,and a TH350. Dyno runs were made back to back. Final number was after about 8 runs. They were closing! Also it was raining out-HUMID 
just my luck!!! Final numbers were 518.3 rwhp 485.5 torque. The car runs good. This was done through a dual exhaust ,dumped before the axle, with bullet mufflers. Car drives on the street fine. Props all the guys at Speed for all the help. The car is sick on the street!

Thanks, I don't have all the nitrous details done yet. It will be soon. I almost have all the parts. I'm going to start off with 150 for testing and go from there.
