Default T3 Gearing Question

Ok, so I'm not new to R/C, but I'm new to lower-winds-than-stock and mod motors, as well as gearing.

I have an Associated T3, and I'm getting ready to put an EPIC 19t Outlaw Pro mod motor in it. What final drive ratio should I look for in order to not gear it too low [or too high]?

Also, I believe I read somewhere that the tranny's gear ratio is 2.4. I this correct?

I know the extra strain of pushing around the T3 will heat the motor up, so I'm going for a mid-range gearing, not too much acceleration or top speed.

The T3 is pretty much going to be run in low grass, asphalt, and maybe some dirt, but rarely.

Thanks for your help!

Well, the final drive ratio thing is lost on me; however, I race with a Team Associated driver and his statement to me on gearing was this: "Always use the stock spur and a 17,18 or 19 tooth inion." NO matter what. That is what he does and seems fine for him. So I would start with 17 and go from there.

Well, I dropped my EPIC Outlaw Pro into my T3 last nite, with a Novak Rooster ESC.

I didn't count teeth on the spur, but I am guessing it is still the stock # of teeth [I bought the truck from a friend of mine, and haven't had the chance to ask him about the spur yet].

The pinion teeth I counted, and came up with 22... which is too high. The FDR is too low with a 22 tooth, so I am going to get some more pinions today, probably 17 to 21 teeth, to go with the 22. I'll probably start with a 20 tooth pinion, since the gearing that was on there was only somewhat low.
