It says torque wins races. Of course that's not true. If it was, we'd all have semi truck engines in our race cars. Horsepower to weight ratio wins races.
And I agree, the Pontiac motor has way too much in to it to only make 650 horse.

Switch the carb and it will pick up power...

Yeah I have serious doubts about that carb design. I would be interested in the back story on the engine design. Peak power is 5900 RPM but the valvetrain and the oiling system appear to be NASCAR type stuff. 7/16 pushrods, Crower rocker arms. Peterson R4 pump, etc. Those are serious high dollar parts. Even the water pump uses a NASCAR style multigroove belt. Maybe it is just designed to look like a NASCAR engine? Could be going into a vintage NASCAR chassis for track days or something. Also has a Wilson bling spacer, real money was spent.

What type of carb booster? are we looking at? Doug Booster? That looks like a derivative of Pro Systems old SV1 carb. I mean, trying to reinvent the wheel sometimes doesn't work when the wheel was invented 5500 years ago. If something was better, it would have been figured out long ago. Same with boosters. All this time with annular, dogleg, straight leg, forget all that.... Just drill some holes in a tube!

An "aerosol" carb. Design has been around for years and not very successful IMO and certsainly not the best way to make power.

Motor Trend and Westech Dyno are a platform to showcase advertisers' products. I remember Horsepower TV around 2012 Built an Edelbrock headed hydraulic roller cammed 440 six pack that made a whopping....410hp. Seems they want us to pay attention to the bling but not the power it makes.
Keep old mopars alive.

I’ve dynoed motors with various versions of the KRE hi-ports. One thing that seems a bit odd to me is the cam selection. You’d think big split and wide lsa would have been used to help extend the power band, yet it’s peaking at only 5900. Seems more like a street EFI type cam to me.
For sure, the hp doesn’t really seem commensurate with the total scope of the build……. At least in my mind.
