Topic: stock manifold specs?

[The_Saj]

ok i searched around a bit and couldn't seem to find this info and not sure if somebody has posted it and i'm just horrible with searching or what...

i'm looking for the specs for the stock exhaust manifold ports... whether the measurements are on the head or the manifold doesn't really matter (and yes i'm aware they are square with curved corners) i just need a LxW or similar measurement. i'd settle for measurements of werks manifold but stock is what i'd prefer.

any info would be greatly appreciated

DDM probably has those figures.

I can get you a length and width, but the port is kinda a kidney bean shape, FYI.

Some pics if it might help

I need more coffee this morning, for some reason I didn't read "exhaust" and assumed intake manifold.

The exhaust manifold ports are 22.77mm tall and 38.44mm wide.

You can go here: http://gmtunersource.com/racertech/ecotec-build-book and download chapter 6 it has specs and measurements on page 102.
