Does anyone know if there was a production 327 with 4 bolt mains?

From what I've heard from salvage yard people, school busses got four bolt main 327s. I have no way to verify that.

Re: Was the 327 ever built with 4 bolt mains?

Possible school buses did get a 4 Bolt 327 but I seen Marine 327's with the 010 4 bolt block in late 68 along with the Forged Medium Journal crank and 291 Heads. Nice Engine if you can find one. I believe these Engines were produced from 68 to 70 and don't know if they where assembled by GM or say by Mercurser or came from a Marine Engine Plant.

I don't believe there where any Automotive PSGR car 327's with a 4 bolt main block, including the Corvette Engines.

No. There was never a factory-built 4 bolt main 327. Anyone can make one out of a later 4" bore block.

The first 4 bolt main small-block was widely publicized for the '69 model year in Chevy Tech Bulletins.

Jay,

Post photos of the mains and the ID pad, if you are confident that it wasn't "made" by someone. Also, picture of the Date code etc.
