367 vs 410 Engines Masters

I'm not looking at peaks but the averages, When I compare engines that have different rpm power bands on the dyno graph, I compare hp horizontally to what rpm each engine makes that hp, eg, at what rpms do each engine make 250hp, 300hp, 350hp, 400hp, 422.hp etc..
I couldn't get a good read on the graph in the video but when you said it's only 8.5 hp more than the 360 those are the peak numbers. Unless I am remembering wrong. Not average numbers. When Abody wagon said it would be cheaper to build the 360 you replied "especially for a 8.5 hp difference." I thought that comparing only the peak hp difference was misrepresenting the complete difference between the two motors.
