I know that all of you guys runnin 4.8/5.3/6.0 are all goin towards the 3000+rpm stalls. Is that becasue the motors don't make torque down low and you want the the motor to run its its power band? My question is that on a big block motor where torque is rich at low rpms would u still want a stall that high or would 2500-2800 b fine?

Aye, on a standard big block from the old school I would not put a large stall on it. Most older 454s and such made peak TQ at 1800-2200 rpms. Most newer small block trucks don't make peak TQ till 3800-4400 if I remember correctly. I know for a fact that the 5.3L and 6.0L trucks are slugs until you hit the 3k rpm mark, then they haul ***...

I'm sure if you have the powerband specs for your motor (peak HP/ peak TQ @ RPMs) you can call any of the main manufactures like Precision Industries, Yank (GM stuff), TCI or Art Carr (the real one in Cali, not Texas) and they could tell you which converter would be right for your big block. The TQ multiplication factor also is very important in your case so you dont hit the tires too hard or lose too much effieciency up top where most big blocks run out of steam.

Back in the late 90's, I think it was 98'. Art Carr sold his business (and name it seems) to another company. At the time they were located in Reno and had just completed a move from Fresno.

A lil while later he decided to keep running the business but by then the other company was using their name and associated history but based out of Texas. So last time I talked with one of the guys at the real Art Carr they were still working with the lawsuit and such to get the name back. Not sure hwo it turned out but here is a link to the company under a new name.
