That's pretty stout
You put down more torque then my 13 did.
I out horsepowered you,but that's not the important number.
Torque is what counts,as horsepower is just a mathematical equation of Torque and RPM,and is only a number on paper
What make of dyno did you run it on.
A Mustang's numbers are usually lower then a Dyno-Jet's numbers.
I wouldn't be disappointed in those numbers out of a 4.7
Mines been on both a Dyno-Jet and a Mustang dyno,but was tuned on the Mustang.
This is my thread on my 13.
