Edelbrock Secondary Air Flaps

(1/1)

SundanceKid:
Are the modifications Edelbrock made to the secondary air flaps on an 1910 worth the time to replicate? If so, does anyone have a 1910 and willing to take measurements? 

Cliff Ruggles:
Complete waste of time, we bend the tabs down and either add a notch at the POE holes, or relocate them under the flaps.....Cliff

SundanceKid:
I've always used a small 1/8" notch (actually it's half a 1/8" circle).

Any benefit to a larger notch? Experience has taught me you can go too big. It has also taught me you can't remove the divider either (I lost a race I should have won trying that one).   

Cliff Ruggles:
The best scenario is always to relocate the holes under the flaps.  Large notches can produce a lean condition, the smaller the better.....Cliff
