Weiland intake bung hole

[Hubbarocks]

got your attention

i have this Weiland 7512 intake , i plan on running on my 440 build. I'm gasket matching it and cleaning up the runners. it's kind of an odd older model intake, but supposed to be pretty nice rpm range 3,000 + (or so i'm told) my buddy gave to me new for a 30 pack a long time ago, fair trade i thought

... anywho… i notice it's got a hole in the center for what i'm guessing is EGR passage or something?? i was just intending on blocking it off the back with a plate i'll fab up. Can i / should i block off the hole inside of the intake ? thought i'd ask if relevant, it may cause gas to puddle or turbulence of some sort? maybe i'm over thinking it.

thanks in advance.

I would drill and tap that for a internal drive pipe plug. You will also need to cover the two hole pad or use a block off intake gasket, if you are using cylinder heads with a exhaust cross over passage.

Looks like a sneaky way to use nitrous!

I like the plenum of my intakes to be fairly smooth with no holes etc. Might take a die grinder and widen the bottom of the drive hole of the plug and fill it with epoxy. With the widened bottom, the epoxy shouldn't ever come out but keep the grind rough for added protection. Have never had one come out and have never dynoed one with and without a smooth plug top.....

this had crossed my mind too, was hesitant to fill it. i have used JB weld to correct head grinds before with no issues.
