I couldn't think of a better place to ask. I would say you guys run more 2004R trannies than anyone. I have a 64 Chevy II with a 406 and a Procharger. I need a converter. I'd like to know who makes the best converter for the money. This is mainly a street car and occasional trips to the track. The motor is making in the neighborhood of 650 to 700 hp. I have a 9in. Art Carr that is stalling around 3600. Hartline did a tune on it and said I have to go to a lower stall. I need to be around 2800-3000. This 9in. is heating up pretty bad in traffic. I was under the impression that a larger converter does not create a much heat. Is this true?
