Split vs Open plenum design
#2
#3
Thanks, that's what I was thinking but I wasn't sure. I think the split plenum is used to get a smaller plenum volume to allow more flow velocity at lower rates as compared to a big open plenum being able to flow more voume at higher rates.
My 460 came with a Weiand split plenum high rise manifold. That should make it a bit better for the street than an open plenum design.
I don't know what cam is in it and it has stock heads. I'm guessing the heads aren't ported because it was built using stock exhaust manifolds. It does have a nice dual exhaust.
