I plan to open up my 9425-B intake this winter when I do some other sprucing up and I found a photo online but now I can't find it again.
It was a top view of the 4 holes but someone had cut out the webbing to help it breathe better. Anyone have that (or a similar) photo?
Thanks.

Here are a couple of mine that turned out very well. They are capable of making good horsepower with professional porting. We made 436 hp with one of these on the 303Y in dyno testing for EMC. We used the Mummert in the actual competition because it was up ~18 hp over the -B. Joe-JDC

Here are some more pics of the intake modification to which you refer.
And here’s the link to the article previously published in The Y-Block Magazine giving some more detail.
