Bought this off here many years ago thinking it may work for my setup. I have a 540 BBC that puts out 800+ on the motor dyno and 1250+ with nitrous. This converter stalled about 6000rpm on the motor with my engine setup. Trying nitrous just pushed through it. Sent it to A-1 (they are close to me) to have them check it out. They said it is in great shape, but completely the wrong kind of setup for my combo. Had them set me up with something specific for my car and need to get rid of this. Was running it with my Powerglide with turbo shaft and a .090 mid plate.
