340 exhaust manifold

[discharger1332]

hey guys just going through all the parts piled in my 66 signet. i found an extra set of manifolds, any one know what part number 4006741 is off of? i tried to do a part number search with no luck. it looks alot like a 273 manifold but doesnt make the hart turn at the flange. maybee 67 &later a body 273? or 340?

Hi, just went thru my casting #'s book and the book covers 1962-74. There is no #'s that high. The highest the casting # goes up to is 3837621 and it is for a LH 74 440. Sorry I cant tell you exactly what it is, but doesnt look like its between 62-74

Little chance it's a 340 or even a 273 manifold starting with 400xxxx, that's likely a post 1975 manifold.

Probably a 318 manifold
