My 75 Duster I have a 360 bored 40 over 358 stroke crank thumpr cam aluminum heads roller rockers fuel injection high-rise 373 gears in the rear end need to know what would be a good stall for a torque converter.
CRT does not build converters....just passes on the specs to the converter company....Call CRT & see what they tell you with your specs.
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.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.
Looks good except for that over-polished flexplateJust bought a 27-25
2500 stall. But it's for a 408 Six Pack with a 904 Trans.

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.
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.They're not gonna build a converter special just for you; based on your individual specifications..

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.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.
