I figure a 719 horse motor should be able to run mid 9's in a 3200 pound car at 140+.
My ex motor( 422 W5) after i sold the car was upgraded and dyno'ed by Best Machine and made 708 horsepower. This is a full on 14 to 1 effort with light rings, gas ported slugs, big roller, etc, etc.
The car( 3200+ pounds currently), went 140+ with this motor in it.
So, IMO, those dyno figures were well backed up at the track.
I have yet to see a pump gas gen 3 run 140+ in a 3200 pound plus car. Once i do, i will become a believer, but until then, its just racing likely inflated dyno numbers..
