The best thing you can do, is call reputable converter builders, and give them all the info, about the engine, and car. Let them tell you what you should have. But don't lie to them.

Just bought a 27-25
2500 stall. But it's for a 408 Six Pack with a 904 Trans.

Call a good Torque Converter company and they will walk you thru it. You need to know your tire size in inches. How tall they are. Easy to find on the tire manufacturer web site.
Call CRT & see what they tell you with your specs.
CRT does not build converters....just passes on the specs to the converter company....
Call the actual maker of the converter....who ever you choose....TA...PTC...Ultimate...ATi.....etc...

I couldn't agree more. GIVE whoever you call, ALL information on what you've got, and what you intend to do with your car. Most if not all performance converter builders have a spec sheet on their websites that give you an idea as to the information they want. Don't give them false information, or your converter will not turn out the way you want or expect. I spent a lot of years in the industry, and have seen the results of over exagerating your combination. Never a good thing.

Looks good except for that over-polished flexplate

Match it to ur cam . Where does the cam start to come alive at ??
There's more than one Thumpr cam. That means any answer you get here might not be correct. Can you please tell us EXACTLY which cam it is? We cannot read minds.

They're not gonna build a converter special just for you; based on your individual specifications.. They're gonna ship you something off the shelf. There's higher stall converters on ebay for 185$ free shipping. They are not available with the high tech sales pitch however..

That’s just wrong. I just ordered two PTC converters for 340’s. Both are 9.5 inch cases but two different part numbers. They aren’t just sitting on the shelf. They build them per the order because they may use a different stator or any number of other things.
Those converters were under 600 bucks and there isn’t a snowballs chance in hell of a 200 dollar converter even coming close to what a custom converter will do in terms of performance, driveablity and street manners.

What he said. The first converter I had Edge make for me, was totally custom. 3.000 rpm for a 170 slant six, with the small pilot nub, and the large input splines. Ordered on Monday, in my hands on Wed, in Florida, overnight from Calf.

I've seen enough of those low buck converters apart to tell you one thing: You get exactly what you pay for. NEVER let price be your guide when purchasing a high stall. Email, call some of the companies mentioned in this post, and many other posts regarding high stall converters. Ask people that have purchased their product what their experience has been with the company they bought it from, and if there where any issues, how did they handle it. The company that I worked for in the past had a 1 year warranty on all high stall converters, and on the hard core race units, they had a two year warranty. Each converter was issued a serial number so that in the event it was returned for any rework as requested by the customer, we could keep a record of what had been done to it.
Buy the $185.00 ebay special if you want, but wonder why it was so much cheaper than others. From what I've seen on ebay, some of those so called high stalls are nothing more than a stock rebuild.

It ain't rocket surgery.. Stock converters are far from junk; lasting hundreds of thousands of miles. It's funny, the same guys who tell ya to fork out $600 for a converter will swear by a 904 behind 450hp. fuggetaboudit.

No, it is not rocket surgery, it is hydraulic science/engineering. Stock converters are not junk, for stock or extremely mild engines. Speaking of stock converters, do you know how many different non lockup converters Mopar had? There were many, based on the engine torque, and vehicle weight, and gear ratio. The OP doesn't need a high dollar race converter, but he should invest in a decent converter matched to his engine/car. Otherwise he is leaving performance on the table.
PS: It doesn't cost a thing to make some phone calls, and get the info from the horses mouth. Then the OP can make an informed decision. If you notice, I did not recommend any size/stall for a converter, or even a particular company. I essentially Just steered him away from advertising hype, and to people that have the expertise to give him good advice.

O'Riellys sells stock 340 high stall converters for $75. It's a 727 converter, but even the big block cars were running converters that cost $75. A stall is a stall, flash or whatever, but the only reason some companies have a great reputation is because they know exactly what stall will make you happy. It's one step up from a fluid coupling. Everything is engineering, but for mild street cars, a converter from a company that makes racing converters is throwing money away. (I'm sure everyone will agree with me..)

Back in the day, we used to go to the junk yard and get a power glide converter from a Vega and put it behind a 350 V-8. $15.00. The equivalent, today, would be like using a converter from a 4cyl K-car (don't think it would fit). We would go thru about 5 per season.
Those that know me, know I'm a cheap SOB, Hell, I spray over 175 HP on stock slant six pistons, but I would not ever consider a "off the shelf converter".
I've said my piece, the OP can make his decision.

I ran the Vega converters from the th350 transs; in camaros and chevelles...way too high stall for the street in a heavier car like that. They were small. Those old used converters held up pretty well; especially considering that they were 50 year old technology; not like the rebuilt ones of today. Stock Chrysler converters are found in one ton trucks and motor homes; so they can't be too bad. The 904 converters crack around the pump slots, so I shy away from used ones, but rebuilt converters get a bad rap, just like cheap clutches for trannys; those days are gone.
