Edelbrock Air Gap

@ou812 Perhaps you can comment on what you have found with spacers on top of the Edel. RPM? As well as a mild divider if you have done such?
Thanks.

Lelo, The spacer adds plenum volume. The nothc doesn't. Thats about the only thing. Build dependent, extra plenum volume may be good.
1" open really improves power from about 2500rpm and up...also cleans up the A/F ratios with most carbs....
