Gears & Axles - Which gears with a PT4400?

I will be adding a Yank PT4400 to my car in the coming weeks and I am still confused about which gear would be best in the rear end? Currently the car has the stock 2.73s in the rear, and I am sure they would not work well with a PT4400. Streetability is not a concern because the car rarely sees heavy traffic. I am mainly focused on Drag strip performance. From what I have read 3.42s and even 3.73s are recommend as a good street/strip combo. However, would I see any performance gain with a 4.10? I have been told with a 4.10 I could run a 28in tire, and that seemly would give me better traction. Would a 4.10 be a good gear for a moderately street driven vechile? These gears will go into the stock 10 bolt and I will be running slicks on the track.
Also which suspension mods would help me the most? I will be putting some BMR subframe connectors on. What else would help give me better traction?
Thanks for the help!

On a mild Head/Cam motor, I've only seen .05-.10 in ET gain by going from a 3.23 gear to a 3.73 with the Pro Thruster 4400...it's that good. If you do mainly street racing (i'm talking street racing from a dead stop), then 3.23 gears would be perfect. If you only race from a roll like the ricers do, then 3.73 gears would be best.

For the track, 4.10 gears with a tall tire would be the ultimate, but you better have a motor that can pull over 6500 rpms to fully use it.

You could even keep your 2.73 gears although they would make this loose converter feel very LOOSE!

I do my races from a stop, like a man <img src="gr_images/icons/wink.gif" border="0">
So you are saying 3.23s would be the best from a stop?

If your primarily thinking of street racing with a TP-4400 with any gear.. better look at some ET streets or look at a different converter.

If your looking for the best(quickest) track combo, 3.73 with TP-4400 offers great drivability and is a terror at the track.

I rarely street race, so that is of no concern. Track use is my biggest concern.
I have gotten two different suggestions here on which gear to get. Any one have a reason why one or the other gear offers a better combo with the PT4400?
Thanks for all the info so far, this is a big help!

I run the TP4400 converter and 4.11 gears with spool at the track and it is a beast <img src="gr_stretch.gif" border="0">

4.10s are a good gear if you have tire. <img src="gr_images/icons/wink.gif" border="0">

I run the tp4400 and 4.10 gears with stock internals. It is a killer strip setup with 28 inch tires but I firmly believe 3.73's with 26 inch tires is the ultimate for stock internals. I have 60ft'd the best of 1.50 but I hit 6500 rpms at the finish line with 26ers which is about 1k rpms past my peak hp and is just plain too tight. I'm keeping the 4.10's since I will now be running heads/cam/nitrous and 29 inch tires but if I were staying stock internals, I'd switch to
3.73's. I agree though that the difference between 3.23/3.42 to 3.73 may just be .05-.1 at the most in et reduction. The converter is damn good.

Right now it looks like my gear of choice will be the 3.73s. From what I read they offer a good strip set up, and also will tighten up this loose tranny for around the town driving. I think 26in tires will be enough for a bolt on car, heads and cam in the future. Again thanks for all the help.
