This Pontiac 400ci V8 was sourced from a 1970 Pontiac GTO Judge Ram Air III, and the seller notes that it was rebuilt before they acquired it in 2009. The engine has been periodically turned by hand, but replacement of the seals and gaskets is recommended by the seller. A seller-provided description of the engine is provided at the end of the gallery. The engine is now offered at no reserve in San Antonio, Texas, with an engine stand.

The 400ci V8 is fitted with Ram Air III-style cylinder heads. A Rochester Quadrajet carburetor is mounted on the intake manifold. Additional components include chrome valve covers, a distributor, a water pump, and an oil filter.

The engine pad is stamped with sequence number 0186872 and code YZ. For 1970, code YZ was used for Ram Air III engines paired with an automatic transmission. Other production markings on various engine components are photographed in the gallery below.
