Torque converter help

[70jimmy]

I am getting ready to finally go ahead with the doubler install and I am needing to purchase a torque converter for the turbo 400.

I have been told to get a heavy duty one furnaced brazed. My question is what stall should it be.

it is for the rig in my avatar, 350 TBI stock, 400 turbo, ORD 203/205 doubler triple sticked locked front and rear axles. I was looking at TCI's site and got confused.

When I put heavy duty in this is the one that comes up, there is also one that is the same except it has 6 mounting lugs so that one wouldn't work for me.

Any input appreciated.

I used their SAt. night special in mine....I thinks its a 1600rpm or something stall, like it pretty well, as with the doubler the rpms get up pretty quickly.

I am not finding the saturday night special for a 400 only 350 375 but there is one that is a street fighter.

Also some of them say wide bolt pattern?

All 400 converters have a wide bolt pattern, most flexplates have a provision for either pattern. A stock 400 converter will give you about 1500 stall max in this vehicle which will be fine for your posted specs. Ant good converter builder can put a 400 converter together for you that is brazed and tig reinforced, the turbine fins are just as important as the bowl fins for overall strength and longevity.

I use a guy here. Well its been a few years, prob because ive had zero problems with his stuff.

The place is called Springs Converters. he can build to your needs.

After I had a brand spanking new B&M converter blow up and wipe out a new trans. Stan cut apart the B&M and I was able to see how they were made, vs. A well built converter.

Also, he can tailor the stall speed, sator strength, and put stronger torringtion bearings in upon request also. You would be surprised how much plastic and weak cast aluminum parts are in a stock converter. Granted a stock application is ok, but stronger is better right.
