Such a car could probably be built as a bracket car for a class like S/G which
runs on a 9.90 index. People build these cars to run as consistently as possible
at or near the index because breaking out means losing unless your opponent
breaks out more than you do. Powerglides rule here as racers have found you
can get more consistency with these 2-speed autos than with other types of
auto transmissions. Even those running Mopar or Ford engines will use powerglides since racing 'glides have evolved into a fine science and adapters
are available to bolt them behind just about any engine. A few S/G Cobras
have been built often with stretched wheelbases up to 120" and air dam mods
on the front to improve the original's rather brick-like aerodynamics. Some were
built with the traditional BBC/glide combo which dominates in the class, but a
few have built them with big-inch Windsors, FE's, or 385's combined with a
'glide. The safety rules get much stricter with sub 10 second cars and the car
needs to be built with a full-encompassing cage around the driver that meets
current SFI specs and is subject to yearly re-certification.
