I went through the same dilema. I didn't really want to put 3.73's behind my blower set-up because I figure that I would be going through the traps roughly at 7800-8000rpm. Oh well...what can you do.

Brian,
$500 seems a little steep for the gears.
At that rate it might be a better path to sell the existing setup and seek a 9 inch.
Are you spinning your engine to 8000 rpm now?
What is the bore and stroke of your engine, what crank and rods are you running?
