360 into 64

Is there some reason for not using a pair of 340 stock manifolds ? I'm asking, since I've never toyed with this body style unless it was with headers.

That is exactly what I am doing. 73 340 manifolds for my 349 stroker that's going in my 65 Barracuda. I'm still collecting parts. I can't see dropping that much money in a set of headers.
