GM fours made the same mistake Ford did with their V8s-they made way too many different ones. The Iron Duke was a decent engine but heavy. The Vega needed iron liners, which it only got aftermarket. They still haven't made the obvious and correct one-half a small block. Or an LS now. With the SBC bolt pattern.

The Chevy II engine is actually in big demand for vintage circle track racers. They can't find 'em.

Pontiac and International made fours that were half an existing V8 and took the same head, Chevy never did. Why not I don't know.

They also don't make a gas and diesel with the same basic block. If I were GM I'd finally put the big block to rest and make a gas version of the Duramax, sharing the block and crank forging at least plus the ancilliaries.

Detroit Diesel did a great thing with their engines. They were made so they could be left or right hand rotation, the inlines could have the blower and/or the exhaust on the left or the right, starter on the left or the right. Chevy (SBC, BBC, Corvair) made it so you could have reverse rotation without butchery, but there are no inlines so it's academic whether the heads could flip. This was very important in marine engines.
