I was quite please with a 10.5 on the day and a novice driver.
I tell people all the time..... you have to start somewhere.
As you can see on the moroso chart, it shows the w/p ratio as 6.55:1 for 125.8mph, so at 3860lbs thats 589hp.
On a decent air day, my friends stocker can beat the moroso chart by over 7%(chart shows hp to be 107% of what the motor actually makes for STP power on the dyno).
