Okay here it is, -- Steve Richmond's guide to successful street racing;  First, get yourself a stiff, light body that doesn't look too intimidating.  Second, get your hands on the largest, lightest engine you can find and stuff it in there as far back as possible, even if you have to do minor surgery on the firewall.  Third, find some regular street tires with a sticky compound, and start with a posi rear end from any reliable brand with around 3.73:1 ratio.  Fourth, and this is the most important part,-- keep it looking and sounding as stock as possible, and tune it, tune it, and tune it some more until you get the combination working perfectly.  Fifth, don't ever run at the strip, keep your hood locked (don't ever open it for anyone) and don't get caught.
