Rear end ratio / power transfer

[71chevylowrider]

Hey Extreme just a guess/theory here. How tall are your tires? That could effect your ratio, if you have say 28-29" instead of 26"-27" it could make a difference in your launch capability. In other words if you have shorter tires, that would effectively give you lower rear end gear ratio to make the truck launch faster, if you had taller tires say 30" it could make it more sluggish off of the line.
