Story
The 1970 Camaro SS 396 sits in the same second-generation body as the Z/28 LT-1, but it tells a different kind of muscle-car story. Chevrolet still used the familiar 396 badge, yet the checked 1970 Camaro data identifies the big-block engines as 402 cubic inches. The SS path was RPO Z27, and the big-block version could be ordered with the hydraulic-lifter L34 rated at 350 hp or the solid-lifter L78 rated at 375 hp.
That distinction matters because the SS 396 badge alone is not enough evidence. Over-Drive's normalized 1970 Camaro data lists the L34 and L78 as options tied to Z27, with different carburetion, valvetrain, rear-axle expectations, and transmission paths. Hot Rod's feature on an original L34 survivor reinforces the collector lesson: paperwork, Protect-O-Plate, engine evidence, intake/carburetor/exhaust details, and drivetrain dates are what make a big-block 1970 Camaro credible.
The public-facing appeal is straightforward: a lower, wider, coupe-only Camaro with Super Sport trim, F70-14 white-letter tires, 14x7 wheels, black grille treatment, SS emblems, power brakes, and the option of a serious Mark IV big-block. The L34 gives the car torque-rich street manners; the L78 is the rare solid-lifter prize, with only 600 reported for 1970. This page keeps the two paths separated so enthusiasts can enjoy the model without turning every SS 396 photo into an unsupported L78 claim.
