EFI manifold for a LA 318.  Interesting idea!

I was thinking it would be a neat way of adding EFI to a LA...........  Run the injection systyem with a Megasquirt, and get better mileage and performance.

that will only work on the Magnum 5.2 with the special heads.....better off doing what Polaraco did and get the whole engine, trans and harness/ pooter from a wrecked truck (pre-94)

they are a "dry" intake.....the passages are designed for air only. It has ram effect built in (like an old 1960's long ram manifold that was folded back on itself while it was molten) but fuel will pool inside because of it's dry design...

It coupld be modified by making runners on the inside, it would just be very long runners, like 15inches long, weld in a proper four barrel plenum to work. Actually more work than it is worth, but for $50, would be a cool experiment piece.

"The
 most significant changes that defined the Magnum was a new top-end
package. Magnum heads featured larger valves with smaller stems, revised
 ports, and a new valvetrain style. The architecture was not
dramatically altered, retaining an 18-degree wedge configuration, the
same valve position, spacing, and length, and the same port layout.
Again, the changes here were more of a refinement, rather than a
complete redesign. Magnum heads featured machined valve-cover rails,
with ten valve-cover fasteners, as opposed to the LA engine's five. This
 makes the Magnum valve covers unique. The intake manifold attachment
was changed to a vertical bolt pattern, from the angled pattern used
earlier. With this change, the Magnum and LA intakes are not a bolt-on
interchange, though other than the pattern, nothing else was changed
dimensionally."

The intake itself has runners that go from the left side to the right side, across the upper curvature of the barrel. The ports open directly opposite the cylinder it feeds, thus giving it about a fifteen inch long straight runner. The inside of the barrel is wide open, about a gallon and a half in volume, the egr valve dumps in the center of the barrel through a tube cast into a supporting rib running front to back. To gain access to the open barrel of the intake, a plenum plate and gasket seals the bottom. A carburetor would not work with this large volume of intake area that is basically stagnant air, where the fuel would literally separate from the air as it was squirted into the intake, but it would give you great power at 5000rpm and above. No, need injectors at the cylinders to work properly, Megasquirt wouldn't be very good on this large opening unless the inside volume was shut up and runners made to guide the fuel/air into the pairs of runners on a V8.

It would be a fun and time consuming little project, but really not worth it unless you had a bunch of time to waste.
