I probably own about the closest 10 second streetable C3, but the 10s and low 11s is on slicks! We can do higher 11s and cake walk low 12s all day long on like Street rubber. We also have a full road race suspension (heavy springs, double adjust Konis), all spherical type rod ends, etc etc (about 12k in suspension). The engine is 4 bolt main, large journal 327, with fully ported LT-1 heads, necked down intake valves, rollers, single plane, 30-30 cam, side exhaust 4 inch collector Hookers, 28 inch diameter tires, 10-12 inch wide rims and we can go wider! A lot of oil cooling and water cooling aides and tricks like a Mercedes Benz 6.9 liter shroud and fan assembly. The car is also lightened about 300lbs. We had NOS on it for quite a time with two stages, and the rear diff was the weak link, so we put in a Toms BOE 3.70, plus we have all solid ujoints, etc. And a roll hoop! We redline at 8200rpms! Timing all in fast, and run it anywhere from 36-42 degrees of advance, depending on what we plan to do, and whether we have good octane gas in it or not! I can race tune it on the street for a race, and return it to street acceptable tune to drive it home!

The entire car has gotten attention, as it just isn’t an engine drop job. Over time, it was developed and that took money! And honestly the sweat tune that seems to handle most all of the new cars is about a high 11 second tune, that is totally acceptable operating on the street! I can run it down the freeway at 80mph in the fast lane, but am watching the gas gauge move!
