Thanks,
I saw on Speedvision this past weekend a Ford Falcon with a Crate 351 that they put on a Superflow Chassis dyno. That's what they said anyway.

They even said that numbers on a Dynojet would be a tad higher because their dyno adds more resistance to the rollers to simulate wind resistance and frontal area of the car. How it would accurately figure all that out, I have know idea. I am just a dumb plumber.
