The Dodge Challenger Message Board

I agree with Dave on the purchase of a used high stall converter. You never know what you're getting. Just because the converter hub looks new, and the paint is shiney doesn't mean a thing. Converters are a sealed unit, and the only way you can truly know the converters condition is, or what stall the converter was built to, is to cut it open. We've seen many, many surprises. Mostly not what you want to hear.
We serial number our converters when we build them so the history of the converter can be tracked. Buy a used TCS converter, give us the serial number and we can tell you what stall the converter was designed for, the original application, who the original buyer was, and if it was ever returned to our plant for repairs or stall speed adjustment.
If anyone reading this thread would like me to mail out some information and the specification sheet we ask prospective customers to fill out give me your name and address and I'll be pleased to mail it to you. There is no obligation. Or if you wish, you can go to our website www.tcsproducts.com and the spec. sheet is there. Just fill it out and ask either Steve or Paul what would best suit your needs. We would be happy to help you chose the correct converter stall for your specific application, be it one of ours or one of the competitors.
The down side of emailing me personally is that I'll be out of town from April 10th to April 27th, so I won't be able to get back to you during that time period.

For an example, i have seen a cam from comp cams that are recomended to use with a stall converter that stalls 2500, are the stock converter then enough? (The only thing that confuses me are the fact that the stock converter seems to be rated that high, i thought it was like 1500-2000rpm) But i understand you guys telling me that the best thing to do is take contact with a manufacturer and get a invidual recommendation.

I see what you are saying. The answer would be "maybe".

The way to tell is to put the engine into gear. If the rpms drop very much, and you have to press firmly on the brake to stop the car from driving off, then you could probably do with a converter that stalls a bit higher.

Ideally you want just a very slight drop in rpm when placed in gear. So that on a flat surface the car just creeps forward slowly when the brake is released.

Okey, thanks for the explanation. With the cam i have in this moment, it is like you say Dave.
