Special torque converter bolts, 350 turbo?

I picked up some 7/16 and 3/8 torque converter bolts for a 32 Ford we are building.

With the 350 Chevy were are using a 350 turbo transmission.

When I wnet to install the bolts in the converter, the converter is a BOP type utilizing nuts and 3/8 bolts.

The flex plate is for 7/16 bolts.


Do they make a bolt for this mismatch of flexplate to converter, a bolt with the 7/16 head, but with a 3/8 thread?

Do you mean bolts with a larger 7/16" smooth shank and 3/8" threads? If so you may be able to find them at a specialty nut/bolt supplier. I would just drill the holes in the converter to fit the larger 7/16" Bolt, much easier.

the converter is not BOP if it takes a nut and bolt setup. BOP converters take either 3/8 x 16 coarse, or 10 x 1.5 metric depending on the year.
the nut and bolts that your using should be fine thread. (3/8 x 24)
you will find that on the flexplate that 2 of the holes are going to be what look like oversize holes, the 3rd is slotted for line up purposes so theres not a problem with the other 2 while bolting up...
theres nothing wrong, just make sure when you put the first nut and bolt on through the slotted hole, then after that, you put a screwdriver between the pump and converter and push the converter flat against the flexplate. then tighten that first nut and bolt up. the other 2 holes will be lined up and you will be able to tighten as you go.
