I'm have my trans re-done sometime in the next two weeks and I need to pick a stall speed. Right now my build consists of:

Stock bottom end
NX Dodge EFI Kit
Intake & PPH headers & true duals
M-1 2bbl
QA1's
Caltracs
M&H drag radials
MSD ignition & coil

Eventually the build will include R/T heads and cam. Way down the road, when this motor decides to take a shit. A 408 will be going in with a bigger shot of nitrous.

I'm having the work done at a local shop named Dr. Evil. http://www.dreviltransmissions.com/46RE.htm

I'm going with the 'street evil' package which includes a 2000 RPM stall. I originally wanted a 2800 stall and I see that Dr. Evil doesn't offer a 2800. Only a 2000, 2500, 3000 and 3500. Would going with a 3000 stall be overkill? Keep in mind that this truck still needs to be street driven.

Also, whats the difference between a lock up converter and a non lock up converter?

2500 would work well, since you're still on the stock cam. 3k might be a bit much, altho there are folks running 3k stalls with stock heads/cam. Ideally your stall speed should be based off of your peak torque, some say a few hundred rpm below peak torque is the best spot, some say at peak torque. But then of course, you also have to balance that with whether it's a street setup or not, and big shots of nitrous will also play a role in selecting stall speed (bigger than 150). Obviously none of that is critical on a mild street setup, just something to think about for the future :biggthumpup:

Definitely a lockup converter for a street setup. Lockup is what you feel when you're in third gear and you feel a lil bog and see the rpms drop a bit, that's the converter locking up, better for highway driving.

2000 is about stock for stall speed. You need a 2800. Do you have to use Dr.Evil? If so, I'd go with the 3000, but I just think it might be too much for your setup. I'm no expert on stalls, so maybe someone else would be better to answer. I basically had your setup with a 2400, and needed about 400 more rpms to get to the sweet spot. You also need a computer flash and throttle body. :biggthumpup:

You want the lock-up version.

IMHO go with the 3000 converter. I had a 2400 stall converter in my 01 & 03 R/T's for a couple of years, when the trans had to be rebuilt I had the converter refreshed to 2800, couldn't tell much of a difference with street driving. I only had the standard bolt-ons, factory cam, still ran fine. You'll get used to the converter pretty quick, only feels odd at first.

Well I did some reading and it seems I should definently go with a lock-up converter. I'm going in wednesday to talk to the guy that will be building my trans to see if he'll let me bring in an Martin Saine 2800 converter. If not I'll probably end up with the 2500.

Here's a converter question. Viper stall - 3800 or 4000? ENough of a difference to matter? Either one gonna keep em from being able to drive in crowded city traffic?

I have a 3,400 Viper behind my 408 and it just sits on redline when you nail it. I wouldn't go any higher than that.
