Is this a stock 200r4 forward drum? Pics inside

[Steve]

I am going through some parts from a damaged 200r4 and I would like to know if this is a stock forward drum. This transmission belonged to a buddy of mine and he had it built in 90's for his low 11 second car. He thought he bought a forward drum for it at that time but of course that was quite a while ago so he is not completely sure. Thanks for help!

It may be an art Carr hardened stock drum but judging by the way the splines meet the shaft at the top, it's probably not a billet shafted drum. I won't pretend to know everything though

It looks to be a stock drum via your pictures. The only way to tell if it is an Art Carr drum is to check both of both ends of the drum shaft. There is no physical difference as Art has the drum shaft annealed for strength. At the top of the drum shaft, there will be Rockwell hardness testing marks. On the other end of the shaft, one of the holes will be welded closed. Early drums, Art had the drums coated to make the drum have a black color.
