Stock Z Comparison (76 to 78 style is missing It
looks like 75 but with more pollution fittings)
Bob Sharp Racing Intake, note the symmetrical
entry of pressurized air between runners 3 & 4
12 Injectors/ 2 Fuel Rails (most
people just use larger flow injectors)
12 Injectors
LD-28 Diesel Intake
These 4 pics show a simple structure. It looks
like bell mouths and tapered runners could help improve things.
One neat tip from the above is that a stock manifold can be chopped and a new
set of runners and exhaust formed. The stock manifold's connecting flange can be
recycled to save considerable machining.
RB-25/26 shaped manifold adapted to an L28e
RB-26 manifold for comparison. Note the bell
like runner entries

Weird and wonderful ideas

Here is a concept for an easy way to improve air flow in a normally aspirated 6
using stock throttle bodies and some fabrication.
Two 55mm throttle bodies each feeding only three runners.
The inputs can be Y'd to a single input and then fed from a larger AFM or
ideally, run from a non AFM/MAF reliant EFI system
