Default 1st dyno number on my 97 SS

well i made 278/305 to the wheels on motor and with a 100 dry shot i made 368/407. i was pleased with the results. does these numbers sound about right for my following mods? ( scratch the exhaust in my sig. i have now the same headers with no cats 3 in. all the way to a magnaflow muffler.

You might of hit a dead spot. TQ converter could help that.

Sounds about right.

Do some suspension mods, like SFC's, Tuned Shocks/Stiffer Coils and a Torque Arm. A TB Bypass, Ported TB and K&N's should freshen up the intake.

I would sure like to hear that exhaust you got there.
An LT1 with LT's and Duals/Dual Resonator's should sound just dandy.

( The Mass air sensors are junk, stock MAF's are good for over 400hp. I've actually heard of some people Losing power with aftermarket ones on )

I think they do. I ran a best of 8.81@80.76 but I also had a 2.1 60 foot. If he had that badass of a launch, I think those times are definitly possible.
