Re: Torque Converter

I have 2 Edge converters and I'm very happy with them. They are built for your combo so there's no compromises. Give them a call.

Re: Torque Converter

Like 'The Cat' said, choose a brand, call them, and have one built for your combo. The right converter makes a huge difference. Anything off the shelf is just a waste of money.

Re: Torque Converter

I agree with Bill but also ran pretty good with a TCI street fighter too. Different combo tho.
I had great results with Charlie at ATI. He made me a 8" converter that drove almost as tight as the 10" street fighter.
That converter (and trans) is still in service in my sons 78 malibu with totally wrong gearing (3.42's) for it and still clicked off 1.53 60's.
He drives it all the time too.
Not that you would want an 8" converter just passing along our results.

Oh yeah, this was/is a th 350 which I think can be used for a 400 too.

Re: Torque Converter

Best 10" cheap converter's I used are the Jeg's XHD models. Lots of different stalls and have anti-balloon plates front and rear, all the good stuff inside and worked great. They are made by Transmission Specialty's, most of them are around $362 bucks. My 4100 stall converter from Jeg's did just that 4100, on the money and it not loose on the street.

Re: Torque Converter

What would you guys consider a good 60 foot for a high 10 sec NA 3600 pound car, 6.80 in the 1/8 mile? ATI no longer makes a good 8 inch foot brake converter.

Mark that's a loaded question lol.. we talking A stock or your average Joe's street/strip full weight car. I'll bite my old 427 ran 6.70/80 in the 1/8 and 10.70's in the 1/4 @3775 the 60's were always in the mid 1.40's that was on a 289 biased slick. I thought that was about right for what the car was,looking back it would have been fun to try a radial slick and see how it would have worked. I know others that have much better 60's but the cars are dedicated race cars. FWIW my new setup has been 1.31 with less gear and converter and more weight...but more power.

Re: Torque Converter

ATI doesn't make an 8" converter anymore or good enough for your specs?
Either way I'm keeping mine, well it's on "loan" to my son.

I have a TCI converter, but not one of their run of the mill streetfighter deals. it's a high dollar 10" PRO-X race converter, so you wouldn't want nor need that.

If I were you, I would call ATI racing about their 10" Streetmaster. People I talk to who had TCI converters rave about them. This one is usually about $550 but it often doesn't pay to get a cheepie off-the-shelf $300 deal. It's hit or miss. You might luck out, or you might have to spend more money on another one. ATI will ask you about approx engine power, rear tire height, approx vehicle weight, cam specs, engine size, rear gear ratio, and first gear trans ratio, just like any good reputable converter place will. If a place doesn't require that info from you before you buy, then it's a cheap peice of garbage....

ATI Streetmaster Torque Converters for Street and Strip use!

Call FTI - they will hook you up. No affiliation with me other than I am a happy customer.

Re: Torque Converter

May 26/09 bought new TCI # 890-240901 .... 2400 - 2600 Stall
http://www.jegs.com/i/TCI/890/240901/10002/-1 TCI 11" Breakaway
Dual Bolt Pattern / Non Lock-up / 168-Tooth / with Front Anti-Balloning Plate
It performed great on the Street and okay at the Track for 10 years in my TH400
See my sig for details

Fall 2018 the Shift from 2nd to 3rd was lagging/slow so in 2019 decided to rebuild the TH400

May 2019 bought a 9.5" Race/Street - Dual anti-ballooning plates (where applicable), triple bearing package,
full furnace brazing, all fins are hand welded for extra reinforcement, bulletproof sprag and stator design
great for bracket cars or serious street cars. Super efficient.
Dynamic Converters / Pro-Formance Transmissions
gave them the needed specs so they could build to suit my Engine/Car and the way I use it

It has performed great on the Street and at the Track
See my sig for details

When my car had the 406 in it running 6.80's in the 1/8 I had my TCI 8" converter in it, 60 ft. was 1.48 at that time. Probably be better with a converter from Lenny at ultimate, that guy knows his stuff.
