The front drum and rear drum and sunshell are 904.
Look at the lever and strut operating the second gear band.
It is custom. I believe the low reverse drum is 727 because of the roller clutch. The sunshell has been lightened, but it is 904.
Build one of these with an sfi Dnj case would be the ultimate
Torqueflite. IMHO, but big $$$ though.
