Chevrolet introduced the 350 cu in (5.7 L) LT-1 in 1970, making it available in both the Corvette and Camaro. It was an optional engine in the Corvette, and available as part of the high-performance ZR-1 option. Between 1970 and 1972, only 53 ZRs were produced, making it one of the rarest Corvettes.
A CAGE code is a unique identifier to label an entity (that is, a specific government agency or corporation at a specific site) that is a CDA, ODA, or MFR of the part defined by the drawing.

The necessary dimensions for the head styles can be found in the standard. [13] [14] [15]
