i currently have just a 600cfm edelbrock carb with a stock dual plane intake manifold, i am upgrading to a single plane holley street dominator manifold. what kind of power increases should i expect? im also puttin my headers on soon with just straight pipes...no mufflers! but back to the original question, how much power? or difference will this add?

 

and the engine is a 350 dont mind my sig!

 

no one knows?

 

Guess it's gonna depend on what you have done to your motor, and the size of your cam, stall, gearing. Unless you have a cam, heads and engine set-up to breath on the top end, this particular intake might hurt your combination as it will be a dead dog out of the hole.
