divided vs open
I think you are going to get alot of responses verying from, NO, to hell yeah, or like the one above.
When i did my 5.3/S475 last summer i did it on a divided flange and used it, one bank into each side.
Now, i suppose the "proper" way is to combine the correct cylinders and all that jazz to have the correct pulses. yada yada.
If your curious if its going to be detrimental, NO, not at all. In your case, it would just be a little bigger housing.
If your worried about the small area between the to openings causing turbulence, knife edge the inside and be done.
Either way, it wont matter.

I am going from a non-divided to a divided setup on my car. Although i am also switching pipe size and routing so it won't be a great apples to apples comparison.

I guess what I really want to know is,,,,,does a split divided housing make more power, or spool up faster than an open one,,,,cause why do they make open, and divided ?
there must be some reasoning behind it !

From what I have seen.
Power no, they make similar.
Spool on divided slightly better (divided housing on divided mani vs undivided housing on divided manifold).
Trq a big difference, divided made more and faster BUT the trq falls off sooner the divided and the open holds it flatter slightly longer.
You wont get a true back to back because a 1.00 divided and 1.00open are not really the same size.
