If I am not mistaken, all service blocks were also machined for hydraulic lifters. They came with block off plugs/pins but were easily converted. Most likely because the '68 427 was a hydraulic engine.
I just disassembled and documented a 427 service shortblock. The date code was an Omega sign instead of a number for the year. Does anyone know what that stands for. It was a service block with hydraulic lifter supply machined, but was sans the ribbing. I surmised that the Omega sign was a code designation used on service blocks/engines. Any opinion?
