Torque converter for 440?

Any recommendations? Stall rpm, manufacturer? Lift: .488 intake .491 exh. duration@.050: 230 int. 236 exh. lobe sep.: 110, .030 over, 10:1, 3.55 gears, 27" tires, cast crank.

What's your cam, intake, exhaust and heads?

346 heads, lightly ported. Performer RPM. 2 1/2" dual exh.

Headers or manifolds? That combo will probably like a 3000 stall.

2800-3k. 3.91's would really wake that up.

With headers going in a 71 Charger R/T. I hear ya but I kinda have my mind set on the 3.55s right now.

My 71 Charger R/T has almost the same cam , TTI headers , portes 906 and a Holley street dom intake . with 355 rear and 275 tire I use a Stock converter (1800 stall 11.75)and I run high 12s at 110MPH . I really hate a slipping high stall converter on a heavy street car. I have also used a 10.75 oem converter (340/383 car) and it had a bit more low end power but seemed to slip alot more. I also tried a Dynamic 9 1/2 when I had a bigger cam (3500-3800 stall)but the car was slower by .1 and 6-7 mph. The higer stall also caused usless wheelspin on the street and the track (I use BFG drag radials for the track).The stock converter in the car now, even with a tall 275 tire will boil the tires from a stop all the way through 2nd gear and has stock drivability. That RB motor has so much low end that you dont need much stall.

I would call coan they were able to help me out. http://www.coanracing.com/
