Lee,

Is that really a Siamese plenum? I thought I saw what looked like stock runners in one of the pics. Do you have a pic of the whole plenum? Or are you going to make this one Siamese?

Is it going on your car?

Cheers,
RH

Cool... for some reason the first pic won't work for me only the second shows up which a picture of the bottom of the plenum. From the bottom it looks like it's opened up real nice but it doesn't look to be a Siamese Plenum. I was wondering if you were going to attempt that yourself because I know its takes lots of cutting and welding. I might take a Fabrication Course at the local Community College and learn how to do such things... My daughter wants me to use my VA benefits to get a PHD but I'd rather get a welding certificate!

Cheers,
Ron

You can probably earn more as a welder

Ron there is no center divider the length of the plenum and 1.5" into the heads, so its a siamese....it is not a monorunner....welded, etc..

Copy... I never heard Mono-Runner Plenum in our circles even though it makes sense. In the old days those all were referred to as Siamese Plenums because they combined two ports into one which is the engineering definition of Siamese.

As far as porting goes, again in the old days you had several different levels of port. One of them was the open runner port then known as a "full port" which meant removing all the material between the runners. Even though they didn't refer to this as Siamese it meets the engineering definition of combining two ports however, we always left that designation to what you call the "mono runner."

Terminology does change, I just have to get use to it. It took me six months to figure out that when my boy said my car sounded SICK that it was actually a good thing...

After all these years I still can learn...

Cheers,
Ron
