Has anyone heard of the 1957 Corvette SS Project XP-64? It was the personal project of Zora Arkus-Duntov, the father of the Corvette. Built to race at the onset, it competed at the 1957 Sebring 12 Hours and is powered by a 283 Chevrolet V-8 fitted with Rochester mechanical fuel injection, aluminum cylinder heads, and a solid roller camshaft. A one-of-one design, it shared little but the grille with its factory Corvette brethren. Underneath its curvy magnesium body is a lightweight and sturdy tubular chrome-moly chassis. One-off Corvette designs are rare, and one with a racing pedigree, built in secret by Zora Arkus-Duntov, is even more special. It sold at RM Sotheby's Miami 2025 for an incredible $7,705,000. Someone had very deep pockets!
my fave racing car of the older ones was this AC Cobra 427 that had, instead of the usual windshield, a small semicircular Lexan or such windshield of about 4" in height curving around only on the driver's side of the car, to reduce drag. It was red and I do not think it had any muffling in its sidepipes. It made a resounding backfire on downshift and trailing around a corner at the track. Quite impressive, and I am sure, QUITE valuable. Also in attendance were really low-slung vintage race cars, some powered by what seemed to be boat two-strokes. It was quite an eclectic mix. The Lotus cars were SO low. You don't really get the idea of how low and miniscule race cars are until you see them in person, and you always sort of assume they are fairly normal-sized cars because most photography is not from eye level, but down low around the car's waist level.
