Re: will i notice a difference?
with that cam and a low stall converter i would stick with the edelbrock for the vac secondarys... if you have over a 2800stall then get the holley.

I would go with the double pumper no matter what. It will make more power than the edelbrock would and be easier to tune as well.

edelbrocks are not vac secondaries. the are called "air valve" mechanicle sec. with another flap above the throttle blades to somewhat meter the incoming airflow.
