What kind of power needed to be in the high 10s???

I know chassis has alot to do with it. My 340 duster runs hand in hand with my buddy's 500 HP 410 duster. He is running a bone stock suspension (with exception of moser axles) with dry rotten bushings, and worn out shocks. The super stock springs, snuber, 3:91s, and 3800 stall work pretty well with the shorter stroked 340.
