Again I said It's kool little engine, But the only really impressive thing about is not it's hp or torque but that it did it with a 195 cfms, Doesn't change the fact that it stop picking up power for the last 1000 or so rpms it's just an observation. But you got to make a big thing about it cause your Cult of the Small depends on this and that Ford 650 vs 750 carb shootout where they end up picking the 750 anyways.
Even if this engine kept making power to 6500 rpms with the 195 cfm head, it would just be kooler engine, wouldn't change anything for me. The take away from that build ain't if your looking to make 435 hp @ 6000 rpm and 430 lbs-ft, the obvious answer is you need a 316 ish engine with a 195 cfm 145cc head, it's if you pay attention to details that generally there's more to be squeezed out if one so chooses.
But most will just choose the 340/360 route for a 435/430 hp/tq with a 230-250 cfm head.
This engine doesn't prove anyone one wrong, cause no one is arguing if you dump a lot of time and effort and money into an engine that you can't get results like this. You only think that's what people are arguing again strawman :)
