383 with Eddy heads!
I would not either but then again, if you look closer, you might be inclined to agree based on how the head flows and both are short stroke engines. Go to Edelbrock.com and bring up both heads in separate windows and look at the head flow and where they start flow the most. The cam lift gets into the best flowing area of the head.Note, not max. flow area.
VIA your statement, it is a correct view, but narrow.
