Secondaries not opening

June 8 2008 at 11:34 AM		Paul  (no login)


Response to Edelbrock 1409 secondaries do not seem to be opening
When the 427 draws air through the 625-cfm Carter AFB that was the stock carb from Chris Craft, those 4-bbl secondaries will open when called upon. However, when the small block calls for power, there does not seem to be enough of a suction demand from the motor to open them, as I have experienced much the same issue you note on your motors. I can hear them opening, but not until way up on the top of the rpm band, just as you have noted. I have not removed the air cleaner to watch what is happening, but that is next.

If you talk to Edelbrock, that would be one real nice bit of info to share here on the forum, please keep us posted.

Regards,

Paul
