I use A-1 Converters also and they have been very good.......not sure although who specs out a converter before the engine gets dyno'd unless an engine wasn't going to get dyno'd and then I think best they can do is ball park it from experience but since you stated that yours is getting dyno'd Monday why did Alan spec it at 5000 prior to a dyno sheet? Seems a 5000 stall might be a little short anyhow but a dyno sheet would prove or disprove that out.
