    I think you mean 12 and 13" switch pitch converters? I have a 12" in Plan II, out of a ST300 transmission, it's been reworked to stall around 1800ish in low stall, and 3000 in high stall, and in hi, it's really loose until it hits 3000. But most of the other SP converters I've owned would only raise 500 rpm, so it depends on how it's built. Hughes is the last one to overhaul a SP converter for me, but it's been 7 years ago.

    I never head of anyone making any of the other parts you need to convert a TH400 to switch pitch, which includes the pump cover (stator support), input shaft, and solenoid. These parts are getting real hard to find, as they were only used in 1965-67 Buick, Olds, Cadillac transmissions.
     
  2. Yes I do.
    Too many years of being around 7, 8, and 9" converters all the time. LOL

    Between '02 & ,'17 , I put 52k on my avatar before I got sick . Only reason I stopped driving is sick = no work , no work means no money for fun , had nothing to do with the manual transmission . Pre 1970 , it wasn't a hotrod without three pedals !
