Edelbrock 440-6 manifold modifications

[Cudatali]

Looking for any intake manifold modification tips or tricks. Getting ready to build my 440. Freshened it up and had it balanced. Got a new set of Trick Flow 240's and a mild custom cam from Dwayne Porter, (if Comp ever gets is shipped out to me.) I'll be using a new Edelbrock manifold, decided to not use the heavy cast iron I already had. Of course will be using all the trick carburetor parts for fine tuning but just wondering if there are any mods that are typically done to these manifolds for improved performance. I will be verifying the port match with the heads but is there anything else that is done?
Thanks!

Port matching comes to mind. This is where one tries to match the intake ports from the manifold as perfectly as possible to the intake ports on the heads. This includes the gasket. You're shooting for a perfectly smooth transition between the intake and heads.

Yup, as mentioned in my post I intend on doing that. Always important to have a smooth transition, agree.

Sweet but damn I can't read it. I've tried printing it in different scales and still very blurry. Can you post the link please?

Thank you!

I found the article, very interesting. Unfortunately they don't discuss any modifications for the standard 3x2 manifold setup.

Do you have the manifold?
I have two. The original A12 is very nice, the much newer over the counter manifold has terrible core shift, and nasty misshapen port openings.
I see you're planning on a port match,, it'll need it,, and check the carb throats. They aren't round, and the core shift leaves a ledge that has to be blended out.

Thanks for the heads up, I will study that closely

Port openings, and the ledge in all three passenger side carb throat.

Hughes Engines has a couple porting options specific to these manifolds. Not sure what each entails.

Wow! Those look like "seconds" that were headed to melt down.

Well, I was given to me, free. But that was because of the failed attempt to plumb it for a concealed nitrous kit. It needs some welding, and some grinding, (and some carbs, unfortunately) but the price was right!
