Yes, the manifolds were the official explanation but the word I always got was that the real reason was internal politics. There was a time when the suits decided that Corvettes would always have the highest HP outputs. I had 2 L78 Corvettes and one L78 Nova - never saw any difference whatsoever.

Sort of the same thing, but I remember a conversation with retired Chevrolet engineer Paul Pryor at Gainesville one year where I mentioned that the 70 Buick Stage 1 had the highest torque of any of the engines at 510 (the LS6 was 500). He immediately got a bit agitated about the games the different divisions were playing back then.
