2004 Chevy Monte Carlo SS
Port Matched Lower Intake
Finished Product
It took me a couple of days (working on this just a couple of hours a night), but I finally finished. The key element is TAKE YOUR TIME!
Each time I worked on it, I did a little each night and would reach a good stopping point. It's easy to look at it and
say "I didn't remove enough material" or "I believe that corner needs a little more work", but if you get too anxious or in too much of a hurry,
you could EASILY remove more material then you set out to do. I'm sure products like JB Weld could help repair those mistakes, but
I would rather not have to try them.
You will see, I took the time to "de-burr" the runners. It took a while to find the right Dremel bit and the right way to work them.
The goal is not to polish the runners. From what I understand, you still want a texture in them to make the incoming
air turbulant to better mix with the fuel as it's sprayed into the cylinder (polishing the runners would reduce that turbulance).
What you do want to accomplish is removing the high spots in the rough texture of the runners.
