    it's a 3200 pound 87 camaro with about 550 hp, p/g ford 9" with 4.71 pro gears 29.5x10.5 m/t slicks. i've been running a 10" converter with about 4000 stall just don't seem to be pulling on big end.

    4000 stall 10" IMO is to tight of a converter a 8" with around 5200-5500 stall would be a benfit. What do you shift and cross finish line @ now ?
