this is what you currently have :shock:

rough and smooth are fairly relative terms, smooth in an intake runner generally refers,
too the mirror like surfaces that were almost thought too be mandatory in the 1950s-early 1960s
but you certainly can,t get a "smooth surface texture "
with anything in a flapper wheel of 80 grit or larger grit

below is a picture I took about 9 years ago, a very early proto type version on my test mule corvette 383 engine where I was testing cams with versions of the custom intake during research.

This is what you want to have (you can almost see the HP) :twisted:

if your just thinking of increased flow, on the stock intake, this approach helps a good deal over the stock configuration, but a good deal more can be accomplished


having used a custom stealthram intake on my personal corvette for many years now and having built and tested well over a dozen custom plenum designs Ive got a good idea as to the flaws in the original plenum design and how to cure those, or with some designs improve the air flow significantly, it all depends on what your goals and budget are (more to follow)
