torque converter solution

Marcohotrod said
throw it in a lathe and turn the hub down

Not a good idea. There isn't a lot of metal on the converter pilot, and it's hollow not solid.

i was all happy to install the tranny took out of the 82 diplomat because it had been freshly rebuilt, and with a hs /lock up sticker on the torque.
so i went to put it in my 67 belvedere and the torque hub is to big to fit in early forged crank.
so i will keep the original for now. the guy at the tranny shop said he has a overdrive
that is for a six . but im thinking that the torque wont fit ether.
i would think that they woud have to swap guts at a torque converter rebuilding shop
any ideas

You will need to get a custom built converter. That is a lockup converter with the pilot (not the hub) to fit your early crank. Any competent converter rebuilding facility can do this for you. Make sure they balanced to match your early engine.
