Time to Choose a Torque Converter

[mike337]

In the middle of my 440 build, and have a question regarding what would be the most suitable torque converter stall for the car.  Here are the specs:

69 Charger
323 Sure Grip
727 Trans built for higher torque
440 Stroker (about 493 Cu in.)
75CC EZ Heads (no porting)
Comp Cam (XE275HL) Intake: 525/275 Exhaust:525/287
Promax built 6 Pack
Planning on headers, but have not yet determined size yet.
The car is for street use, but may see a trip to the track to see just how fast it really is.
I'm thinking it should be nothing too radical, but still be able to take advantage of the Stroker potential.

Unless you find someone with the exact same car as yours, a message board is the very last place to get a converter recommendation.

Converter design is dark science, get a recommendation from a converter builder or two.

I've had good luck with TCI. I would contact their tech dept. and get a recommendation from them.

Dynamic 11in would be my choice with that cam and those gears

There's your rub. You can't have your cake and eat it too. With the big engine and relatively tall gears, a tight converter will be a real pleasure to drive. But, to max out at the track, you need to let the dog eat, and you have to drive around with a loose converter (something that I really dislike personally) I would recommend using a converter suitable to your primary driving style, and let happen at the track whatever comes. Don't look for the last few tenths at a penalty to your 99% drive time.

Once again, a custom builder can make a small converter tight for daily driving and still have a decent stall speed when coupled to a brutish motor.

Mass production outfits like B&M/TCI will give you a recommendation based on your setup but will most likely just recommend one of their off-the-shelf units.

I am not looking to bracket race the car, or win consistently at the track.  I just mentioned that eventually I will take it to a track to see just how fast it is.  The car will be used on the street, as a normal, pump gas, comfortable ride that just happens to have a lot of horsepower and torque available when the pedal gets mashed.  I would rather give up tenths of a second time potential in a quarter mile for street-ability.  Just thought that someone may have already gone down this road and had a recommendation on a converter that had worked out well for them.

A few converters that I though might be suitable to my combo are the B&M Holeshot 2400, Hughes StreetMaster, and the TCI Breakaway.

Any comments on those converters?
