Okay here I go again going to the pros, I have a 396 that has 425hp and 450lbs torque, and match it up with turbo 400. My question is what would be a good torque converter to use? I want a weekend driver that can be fun at the lights. Not planning on strip driving, but would like to be able to, and want decent low end and good cruising. I have looked a B&M holeshot, TCI, and a few others, what I think would be good is between 1500-2500 stall speeds. Any thoughts or suggestions?:thumbsup:

We need to know the cam specs and rear gear ratio.

Not a pro,but this is my combo and am well pleased. 468 TH400 4.10 ACC Brand 3000 stall. Cheaper stall converter,but have not had any trouble.Just call and talk to what ever company you decide and they can answer any questions .

I believe the stall speed on your stock TH400 torque converter is around 1700-1800.....What gears are you currently running?......I had a 70 Chevelle SS454 which was a blast at the lights!, it had a built & beefed TH350, 12 bolt posi, 4.10 gears and a 10", 3000 stall converter, which is ideal for street and strip......You'll have alot of low end slippage with anything higher than a 3000!

My 4000 stall converter is surprisingly tight just cruising around.

Whatever stall speed you come up with just make sure you buy a well built unit like ati or coan. You will be far ahead to spend the extra money in my opinion.

This is the key if you want a efficient and not sloppy converter.

This is what happens if you buy a cheaper off the shelf type unit

Okay this is good and this is what I have for Cam Specs
Comp Cam
@106. intake center line
Duration @ .50 intake-224 exhaust-230
Lobe Lift Intake-.3010 exhaust-.3010
Lobe separation intake-110.0

For the rear end I have a Ford 9" with 3.70 gears
What esle do you need??? Thanks for the help

With that cam, you could easily get by with a 2000 stall converter, especially if this is mainly for street. If you want something a bit more radial, then maybe 2500.

.........that's why I installed a Coan torque converter in my Turbo 400:yes:.

With 3.70 gears, you'll have a blast with a nice 3000 stall converter!:yes::thumbsup:

since it's mainly a street driven car stick with a 2500 stall I've run a couple on the street and at the strip over the years all B&M and I have always been very pleased with the way they feel and run.

If you're going to go through th touble of installing a converter I wouldn't go any less than 2500. If you had a little more cam I would say 3000 for sure, I would personally probably still run a 3000 even with the cam you have. If you buy a good converter you can always send it in and have it adjusted. Most decent companies will adjust it at least once for free. Meaning you can start with a 3000 and if it's too much send it back and have it dropped to 2500, it works both ways. I'm sure you have a decent company somewhere in your area. Don't overlook local tranny shops in many cases they work with a converter company and you can buy locally.

Thanks guys I will look inrto the names you suggested and see what I can find. I will let you know when it is done. Again you guys haven't let me down, thanks.
