Any specific brand on the gearing?and what gearing would u recommend from 323 or 342?

I don't think you'll notice much of a difference with either unless your a big drag racer and worried about rpms, etc. I went with 342's because they were a lot cheaper for a Moser 12. Not too familiar with 9's.

The calculator I used said that I would be at 64mph at 2,500 rpm with my th400, 3.25 rear gears (9") and my 325/50 tires (28").

The same calculator said that you would be at 75mph@2,500 rpm with that gear and tire.

Of course all of these numbers could be different depending on the "slippage" of the converter. These numbers should give a ball park figure as to what you are looking at.

I run an 80 with 3.08 and 28" tire. Cruise Rpms are around 1800 at 70. The gear loads the turbo hard.

Would it be that big of a difference from 3.25 to 3.08?because I will be ordering a set of ring&pinion set on Monday.

3.25 and 3.08 are close.

I would leave the 3.70 in the car if you are going to drag race it.
