Original small block “rams horn” exhaust manifolds (produced up to 1979) can be said to flow efficiently. Their flow may not be optimal, but they are better than many of the original equipment manifolds. The idea is to reduce back-pressure while tuning the flowing exhaust gases. The center exhaust ports on the OE cast iron manifolds dump into a rectangular box that the outer cylinder exhaust gases flow into. This mixing of exhaust gases so close to the cylinder head and exhaust valves hurt engine performance from lack of flow.

1965-1968 Corvette disc brake systems were a major technological advancement at their onset. The early Corvette design utilized “fixed” disc brake calipers, used until 1968. When disc brakes became commonplace in 1969, “floating disc brake calipers” were used. Floating calipers slide on a ways system, repositioning the caliper as the disc pad wears. This sliding or floating caliper proved to be a good thing, allowing for discrepancies that the fixed caliper would not compensate for. From 1969 on, the majority of vehicle manufacturers used floating disc brake calipers for easy serviceability. GM utilized the early style fixed calipers on the Corvette until 1982.
