1970 Chevrolet Nova SS 350
The 1970 Chevrolet Nova SS 350 is the small-block Super Sport path: RPO Z26 Super Sport equipment paired with Chevrolet's L48 Turbo-Fire 350. The cited Nova references list the L48 as a 350-cubic-inch, one-four-barrel engine rated at 300 horsepower, and production tables separate it from the 402-cubic-inch big-block L34 and L78 cars. That makes this page about the factory SS 350 record, not a generic Nova with SS badges.
The L48 was the volume 1970 Nova SS engine in the checked production tables: 13,991 of the 19,558 reported SS cars are listed as L48 350/300-hp builds. The same sources put the SS package in context with simulated hood air intake, simulated fender louvers, a blacked-out grille, 14x7-inch wheels, E70-14 white-stripe tires, power brake equipment, and available heavy-duty or special performance suspension paths.
Authentication still has to stay disciplined. A cowl tag can confirm the 1970 Chevrolet Nova V8 two-door sedan body, paint, and interior trim, but it does not prove the L48 drivetrain by itself. A specific SS 350 claim needs original documents and drivetrain stamp evidence that align with the engine suffix, transmission, rear axle, build timing, and factory equipment.
