  • trans/torque converter ?

    I ran into an issue with the new engine. the stroker kit is an internal balance & of course takes a different flex plate. the old torque converter lines up but
    will not fit flush against the flex plate. it should go another 1/4 inch but due to the design of the converter it hits the flex plate to soon. this is a 12" converter
    which surprised me so what I am asking is...anyone up on converters & could recommend what is needed / Thanks

    edit = car has an FMX trans

      Mike, the builder picked out the kit & all I know is it`s a Manley crank (3.850 stroke), Auto Tec/Ross forged pistons with Scat rods.
      the flexplate is a 164 tooth by PRW #1830210

        Sure the flex plate is on right? Some you can put on the wrong way as well as the right way...

          this plate can only go on one way but thanks for the reminder. wouldnt be the 1st time I did something bass ackwards.......

          I did talk to the builder & the man he used for all transmission work passed away 2 years ago. he has not found anyone else with
          the knowledge & experience that the old timer had.

            What is hitting, the hub or the mounting pads? If it’s the hub, you might have to have it turned down a bit.

              Are you sure that the torque converter is engaged with all three keys, input, stator, and pump?

              I like to hold the converter by the stub and spin it and count off each engagement.

              BTW, make sure that you use a new front seal or you may be doing this again soon.

                I lifted the engine out & then removed the converter. putting the converter against the flex plate shows that the raised area around the center is
                keeping the converter from fitting against the flex plate correctly.
                the raised area on the converter is 8 1/2" in diameter where as the recessed area on the new flex plate is only 6 1/2" in diameter.
                would the new flex plate require a converter smaller than the old 12" converter ???????
                maybe a 10" converter ?

                thanks, Keith

                  Keith, do you have a pic of the flexplate you could post? You cant use a stock flexplate?.

                    the stroker kit is neutral balance so it needed a neutral balanced flex plate. old plate is external balance.

                    the engine builder said if it comes to a dead end he could re-balance the old flex plate to neutral. I`m not sure I want to do that as it is worn a bit
                    on the teeth & the bolt holes are sloppy....... so I may end up having a stock plate balanced but they are not as strong as this performance plate.
                    the builder would rather a performance plate used due to the hp,torque & compression of this engine.
                    he is trying to get more info on another torque converter for me & I am trying to get in contact with an old timer Ford guy but not having any luck.
                    a lot of these companies & people do not know there were differences in trans models,torque converter bolt patterns, etc..... so we are trying to be careful &
                    not end up with the wrong part.

                    thanks guys, Keith

                      It doesn’t have a pilot bearing or bushing in the end or the crank, does it?

                        no sir, just the usual pilot set up/size.

                          I'm having a hard time visualizing this. Could you get us a pic of the new and the old flexplates and the converter so we can see what it hitting?

                            1st pic-old flexplate & torque converter.....
                            the indented area of the flexplate is a bit over 10" in diameter. on the face of the converter is a raised area (10" dia.) that fits into the plate.

                            next pic is the parts joined........
                            it is hard to see but the shoulder of the studs on the converter fit flush against the plate.

                            now the new plate. the recessed area is 8" in diameter so when the converter is mated to the plate, that 10" raised area of the converter hits the plate before the shoulder of the studs meet the face of the plate. when mated there is almost a 1/4" gap between the shoulder of the studs & the face of the plate. the studs come through the plate just enough to start the nuts on them.


                            sorry, I`m not good with pics or explanations. hope this helps everyone to visualize the issue.

                              So, I dont remember the exact details, but I had one converter/flexplate combo that did something very similar. (I kinda think it was a stock flexplate with a big diameter mounting pattern converter) However it was not a stud mounted converter, so what we did might not work. So, we found a washer that was just a touch thicker than the gap, ground one side (edge, corner, took one rounded area and ground it so it would fit within the lip) flat so it would sit down on the flexplate. We then bolted the converter to it that way and let the converter sit against the washer which was against the flexplate. But like I said, that was a bolt mounted converter, so we werent dealing with a fixed length like a stud is.
