I did some similar work to my 400-2 intake and always wondered what these things were supposed to accomplish. I removed them in when I matched the intake to my HVH/NxExpress N2O plate. Thoughts?
I have been wondering about those same areas on my Indy small block intake as well
By the way John, very nice work on yours! I notice you really got down into the plenum- what is the benefit of flattening those walls out like that? (hopefully I am making sense lol)
Thanks Matt. At that point the only port really shaped in enough was #3 and I just wanted to get some numbers to sleep on as I will be spending lots of time clearing snow from my driveway. Warm-up coming this week and I want to get the Duster home hopefully next Sunday. I flatten the walls and will be playing with some different shapes to get some needed volume to help slow the head speed down some. I will try to get 10-15 more cfm in the mid lifts. 3 and 6 are a struggle as they have to navigate the pinch on the short runners. I'm glad I don't have to pay myself by the hour.
So flattening and angling the walls of the plenum in these pictures is to help slow down the head speed?
My intake is already port matched, but I was thinking about doing some plenum work to it....The question Jeremiah brought up and seeing your pictures has made me curious to the benefits (if any) of the stock opening vs. how you are flattening and angling the plenum entry area.
In you case with the Indy head I can't tell you how it will respond or if its needed as much. The Edelbrock head is so volume limited you will get one area slowed down and then the next limited area needs work. I haven't cc'd one in a long time but I will on this set of heads to check port volume. I am then going to pour a mold for later reference. If you check out my flow numbers check out .700 lift and you can see how the intake helped. If you never made a mold of a port do it sometime as its very interesting what you can see. I have a website saved from the place I buy the mold compound if you are interested. What cc head did you end up getting?
I have never even heard of pouring a mold of a port..have a link to the site that sells the stuff?
My heads are the 360-2 230's (CNC)

Mshred, this is a picture of my Indy intake that Brett Miller ported for a Engine Masters motor that I now have with the 360-2 heads. He also put a adapter for a 1050 Dom. on it. But it is a 4 hole adapter.

This is the company I bought it from but I will try to check my stock to see what number I bought. Don't forget to clean the port good and use a mold release. http://www.uscomposites.com/moldmaking.htmlIts really nice looking at a 3D port.
1970 Duster
Edelbrock headed 408
5.984@112.52
422 Indy headed small block
5.982@112.56 mph
9.42@138.27
Livin and lovin life one day at a time

Damn, Brett does NICE work! It would seem based on the way he shaped yours that it might be a good idea to leave mine alone instead of flatten/straighten like John has with his for the eddy heads..with 230cc's I would imagine that shape helps
