No, crickets.

Interesting engine. It is the earliest known production ZL-1 block [053] casting.

The block we acquired from Lamar Walden in the '80s via McLaren Racing was a Pilot casting. No casting date, sequence number or main cap stamping. Had not been run with a mechanical fuel pump. Later bare block castings had the same ID markings as production ZL-1 engines.
