post of yours 10-15-2014 10:46 am second pic down bottom right of plywood there is a manifold that would work, is that the same 318 one I have or is that a 340 one? with a larger outlet?
I'll have to check but I've been doing this so long that I can tell you that the center dump manifolds (there are two of them in the pic) in that pic 10-15 at 12.46AM are either a stock 318 1 5/8" OR a center dump 340 w/1 7/8" hole. They both have a very similar design and look almost identical except for the size of the exit hole. From the ridge across the back I would they are 340 small hole (1 7/8").
I just went to my garage to check and as it turns out I have ONE 340 small hole (1 7/8") left in stock...thought I was sold out of these. Here are some pics of what I have in this style.
