3100 at 70 isn't too bad, especially if you aren't going to be doing that very often. But at those times, overdrive would come in handy. As with anything, you can get pretty much what you want, all it takes is money. Here's a 200-4R that will take anything your engine can give it: http://www.cpttransmission.com/catalog.htm
One of the nice things about a 200-4R is it slips right in place of a T350 or T400 without driveshaft length modifications. The 700R4 is a totally different trans from the 200, and it's about 3" longer too. Some people like the 200 over the 700 because it doesn't have such a drastic drop in gearing between the 1-2 shifts. One thing to consider though, the aftermarket is flooded with 700R4 goodies.

Any properly built TH400 will not break under the average street -strip use. I know I've said this before, but even a properly built TH350 can easily handle 450 hp and not self destruct. Mine has had some awfully hard useage, and still have not given me any grief over the last 25 yrs. I'm somewhere over 450hp, so I can say it definitely handles that much easily.
You can buy a TCI streetfighter, or competition model for under $1,000, depending on whether you want or automatic/manual shift, manual shift. You'll need a torque converter also, which will set you back another $200, or as much as $480 for a really high stall speed converter.
TCI also sells the TH400 for slightly more money, if your set on a TH400.
Either way you should be able to get a good automatic for around $1500 complete.

T-400 for the win,best toughest trans for the money.
As little as you'd use the overdrive I can't see spending the extra money.
If gas mileage is a concern forget it,you already said goodbye to that when you decided to go rat.

although now that i think about it, a th350 would be easier to install since i already have one and found some that can handle the power. so its either the th350 or 400

i found a local trans shop that will build me a th350 to handle the power for around $900, a th400 for around $1100 not including driveshaft mods, and a 700R4 for around $1300. The Th400 would be super strong and nice but the TH350 bolts right in lol im not sure which to get! decisions, decisions lol
and they all come with a 3 yr warranty including labor

Be sure to ask them how long they've been around, and if they can give you any references from other customers who have had hi performance builds done at their shop!
The 3 yr. warranty is great, but ask them what that covers? Labor, parts, complete; or what? Don't ever mention going racing with your car, as most shops exclude that from any warranty, even if it's only once!

so the th350 will hold up even though the output shaft/front slip yoke is smaller? and do you think i would bust the drive shaft/u-joints out with the th350?

ANY transmission can tear a driveshaft out, or blow u joints given enough engine to do so. Wouldn't matter what you chose to install.
I've blown 3 or 4 rearends until I built a 10 bolt that could handle my engine. I've never blown the TH350, but I did wear it out and had it built back in the late '70's, so I'd say it held up well.
I've also never blown a driveshat or u joints, but I did replace the u joints every year when I was racing my car. I haven't replaced them in the last 10 yrs., so they aren't a problm either. I've never replaced the original slip yoke, and it sttill doesn't have any slop.
