66 Caliente, 390 out, 460 in, what bell 2 use

I have a tired 390 in my 66 Caliente. 460 going in, what bellhousing and flywheel can I use with the factory 4 speed?

429 and 460 are the same.  i think 351m and 400 have the same bellhousing.  i think you will have to use the 429/460 flywheel though.
