I am going to be sending Cory my BMC race manifold, it has a 3L plenum. Only thing is the runner length is setup for more along the lines of turbo. However runner lengths from what i was talking with James about has more to do with where your powerband is going to be from than turbo vs n/a. He specd my runners for a powerband from about 6k-9500-10000rpm so the runner lengths are about 6" or so from the head flange to the top of the velocity stacks. His velocity stacks and plenum design, shape, and volumes have proven to make great power topping many many more expensive manifolds out there both turbo and n/a.

So even with the shorter runners. I think for Cory's setup it should still do well and really improve flow on the topend. The runners are all heavily ported, smooth, and really flow well on a flow bench which is how he originally tested all of his runner and plenum designs. So we will have to see.
