I think your numbers are entirely accurate. I also think the McNicholls, not so much so. I think most of his are computer simulations, much like some of the "Hot Rod" articles that have been published.
I've seen 3 real engines dynoed. Two of them made more than 200 Hp, one made 192 Hp. All three made their numbers at less than 4500 rpm. All of them were run on the same dyno that does both Bonneville Record setting engines and engines that then go on to compete in the Engine Masters Challenge.
