No ZL-1 Camaro had a Yenko block.
Chevrolet produced the last production ZL-1 block castings [3946052] early August 1969. Lockport [LC] did some 053 castings in the late '80s. The 2025 Chevrolet Performance catalog still lists an 053 block casting, much improved over the original. The 3946074 head was produced into the '70s.
