Intake Mods, do they really work?

That's a pretty awesome improvement. So, you just cut down the divider .250? Any other blending in the plenum? Was wondering if I ruined my ld4b or not.

Yup just cut it or grind it down and clean it up a little. The plenum on yours looks good, no worries there. It seems to help the carb get a much better signal and lets the entire engine have access to the entire carb.
