Grudge match HELP!

Dusters by the way mother Mopar made them have more weight on the rear wheels.
With his having drag radials?????
You need more gear and traction to beat him.
Your motor sounds like it is stronger, what are your 60 ft times?
RPM at the traps.
Your car has a 8.75 so find a set of 4.30 or 4.56 gears, drag radials and I think you will have bragging rights.
If he dont have a 4" arm in that motor he is not telling you about.
