Reply to "roush motorsport single palne intake"

Look at the picture that George posted and then the first one.
Did you notice that they look like the same casting?
Now look at the thickness of the flange at the end of the intake ports where they meet the heads. Notice the difference.

The 9.2 is going to have a flange around .250" thick. The 9.5 is going to be .300" thicker.

This is the case of the manifolds that use one basic casting for both. The intake for the 9.2 is going to have more material milled off the mounting flange.

Here is the picture of the special small port a331 torker. You may at first assume that it is the size of a C302 port but it is actually much smaller.
