1973 340 flexplate

[m&mmike]

hi. I want to know if there is a flexplate which bolts to a 904 that allows one to not have to balance the torque converter. thanks mike

I may be wrong but I believe the 340 is an internal balance.

B & M used to make one for the 904 for the 73 340, no longer available unless you find one used. B & M makes one for the 727 that is a little bigger but also works on the 904, it may require a little grinding on the nose of starter. I used one with a newer starter, 94 5.2 ram or Dakota, and have no clearance issues, B & M part number #10235
