Not sure what you are trying to say, but it sounds snarky. When you make statements that are untrue, other readers realize that you are just being argumentative, and this hurts your credibility in the future.

For those who like to learn about some of the old Mopar history, go to ALLPAR.com, type in "dyno testing" and search for an article by Ed Poplawski. He ran some of the dynos back in the 60's and 70's. He also ran dyno #13, which was used for high performance engine testing. There is also some interesting photos of the dyno rooms [they called them cells]. With all the tubes and wires hanging off, the engines look like they are on life support.
Facinating article. Reading it now. Thanks for the info!
