Modifying stock Multipoint Intake for HP?

[MopART]

Just wondering if anyone has had any experience with, read, or heard anything about modifying the stock EFI 360 intake to produce more HP.

I don't know if you are refering to the pre-1992 Throttle Body Fuel Injection manifold on the LA series 360,
or the post-1993 MPI 'beer barrel' manifold on the Magnum 360.

If you are interested in the Magnum 360 MPI, there are 3 pictures of the 'chop and fill' mod at this website, about halfway down the webpage:

Hughes Engines also has a few pics of a similar modification:

I haven't read it myself, but I have heard that one of the magazines (Mopar Muscle?) had an article called 'Inductive Reasoning' where Hughes explained their logic in making the modification, with some dyno results.

The plenum on the 360 Magnum seems to be very big, and the center divider seems to be there to 'almost' make this manifold a dual plane.

Hank,

Thank you very much!!! It must be in either June, July, or August issue - those are the issues I'm missing.


thanks again,
