440 exhaust manifolds

[tricky lugnuts]

Does anybody have any information about the exhaust manifolds -- i.e. original application, etc?
1. Drivers Side 3751068
2. Pass. Side 2899879

I can't match either of those numbers exactly but they appear to be a mismatched set.  Just going by the part number, it seems like the passenger side is from about 1969, and the drivers is about 1973-74.  Someone will be able to tell exactly though I'd bet.

          3751068 is looking like a left  LH for a  73-74   400 -440 HP  b-body ......   but 2899879   

******  EDIT*******    just found this  2899879 is the casting # for a  right side 383-440 HP   1970 -71 b-body

Awesome -- both are 440 HP manifolds. Thanks for looking them up for me -- I need to get a parts # book!
