Upper intake question...
I have my throttle body off, and looked inside the ports on the upper (plenum) there are two protrusions, like rails going accross the bottom of the ports. Is there a purpose for these? Could those be ground out for increased flow? This is an 86 L98. Thanks for your input! :flag

You can port the plenum and ground down the 2 walls behind the TB.
Not much performance gain though, I didn't gain anything.
I beleive the entire TPI has to be ported for any benifits.
