What if Chevrolet had said yes to Zora Arkus-Duntov and built 1100 Grand sports ?

The SPF Grand Sports are true to original. they have the tubular chassis and modified suspension as opposed to the standard C2 stuff. Keep in mind there are two levels of SPF GS: the street cars that have some creature comforts added and the "race cars" which are built by Duntov Motors based upon the GS design.

Either is potent, but the "race car" would not be a fair comparison to a street Cobra. However let us tweak an SPF MK III up and then lets go!

Sounds like a nice article for a future issue of Kit Car Builder, Road & Track, Car & Driver or Classic Motorsports.

I think once you outfit the SPF GS race car and the Cobra to like-raced specs, then let's see what happens.

Having owned a '66 Corvette Convertible with a 540ci BBC (600+ HP) and the Kirkham Cobra (600+ HP), the Kirkham would win hands down, but then at 2,128 lbs, it's about a 1,000 lbs lighter than my old Corvette.
