3.2 intake rib/support delete?
These ribs are starting to annoy me.
Anyone ever grind them off? Do the serve any other purpose other than support the blower and act as a heat sink for the intake air? Thanks Bill K

Thank you Bill.
Itīs a 3,2 ROW engine from 86. While you are in you could also remove the scars from casting between the intakes. |

Here's my intake manifold after several hours of prep and finishing - soon to be installed.

Here is a 3.2L intake in Perma chrome (ceramic coating)... casting marks removed... but I kept the bracket you are inquiring about to mount my coils to....

The real benefit comes from having the runners balanced to each other. Before ExtrudeHone process, they were 50 to 70CFM difference between all 6 runners (IIRC), and after the process, it was less than 5 CFM.... For my engine, I wanted it to be as balanced as possible, as much HP as I am looking to get out of it..... Brad

FWIW, I recorded some in-process deletion pics.
 I wonder if there's anything here I need? Oh well.  Now it's a "lightweight" intake manifold. This is about 2/3 of the debris:  Sherwood |

What were your plans for the support for that long tube that leads to the venturi gizmo, if you chop the bracket? Just leave the tube dangling? My understanding is that the tube can be eliminated entirely if you don't need the brake booster. I'm guessing you use a brake booster though...
