4 speed or 6 speed behind a Pontiac 400?

[T/A Addict]

I am wanting to put a manual back in my 69 and evaluating options before I buy. I have a chance to buy a T10 complete with everything needed for about 1k but the thought of just spending some extra to go T56 may be worthwhile. The cost is always a factor in my decisions but don't mind saving up a little longer if the added expense is worth it.



I know that nowadays T56s are easier to come by and all the accessories needed seem to readily available.
