I am considering the Holley 0-81670 Street Avenger carb. from what I have read it seems like a good performer. The intake I was going to use it on is a Edelbrock 7104, Edelbrock says you can use a square bore carb. on this manifold. Holley says use only on square bore intake. Will this combo work or will I need a different intake for this carb.

That manifold will fit either a square bore or a spreadbore carb.
