Going to order it today I think. Which would you go with? I am going to be running a 408 Paxton Supercharged R/T. Should probably be going about 2800 to keep it some what street friendly and still be able to put down some good times. Opinions welcome.

Call Precision and talk to them (www.converter.com), tell them all your specs and dyno #'s and they'll figure out a stall for you. Depending on where your peak torque falls, you might need more than a 2800. With a quality converter, streetability shouldn't suffer, even with a higher stall speed. :biggthumpup:

I've heard good things about ATI too, so might want to call them both. I've only dealt with PI and they were great.

My old 02 which is Sean's now, has a Viper 3200, which wasn't to unfriendly on the street. but I think you will want more then 2800 with a blown 408:drive:

Chris was thinking 2800 but I was thinking at least 3000 if not 3200.

What kind of horsepower are you running? Any power adders? What kind do you have? Where are you in Maryland?

I have a 2800 viper... i'd suggest 3k+ for your build.
I almost ordered it from Zendak?? Guy whom sells spintech here...but spoke with JM about something else and he gave me a decent deal on one. I'd order it from one of those two.
I think it has a 1 year warranty and 2 year free re-stall (send it back and they can change the stall speed) or vise versa?
