    I'm looking at a 1964 caddy 427 and a turbo hydromatic trans read it was a one year only with a variable speed converter? Will this set up work in a 29 ford sedan or will it shift weird they sell adapters to put standard gm trannys behind it or will I be ok with the original trans

    429? The Variable Pitch 400 works like a normal one, with the addition of variable torque converter stall speed. You can leave it disconnected and have it be stuck in "low stall" all the time, or put a toggle switch and feed it 12v when you want "high stall". The difference in stall speed with a stock torque converter is only about 500 rpm. I have these things in all my old Chevys....love them!

    The buick with the variable converter shifted weird and would almost fight it self stopped in gear the tranny shop said because it was designed for a 4000pound car not a 1800 pound car and was a converter problem????? Just don't want to have that problem again

    ...if I were using a caddy 429 I would just get a regular turbo 400 to put behind it that uses a regular convertor.

    So you don't know if the problem was because it was a switch pitch converter type transmission, or if it was because there was something wrong with the transmission? I guess it's pretty easy to just say "they're all junk" than it is to fix whatever is not working correctly.

    Having the variable pitch converter gives more stall speed, that's a good thing. But you have to install it properly, so it works. It's not difficult.

    I have a switch pitch T400 in my Model A and it works fine.
    You can disable the solenoid that activates the switch pitch
    if you have problems. Its not a big deal.

    I'm running a '64 429 from a Fleetwood in my '29 Chev, can anyone post a photo of the harmonic balancer installed, someone has installed a bolt into the crank to hold it on. I pretty sure it doesn't need this as the balancer is a press fit. The 390's up to '63 did need the bolt. Thanks for the photo of the starter mount front support, mine didn't have one.
    Has your engine got a factory adaptor between the engine and the trans, I believe they were installed after a factory fire destroyed the assigned T4oo's so they used Buick pattern units.
