But looking photos of either stock or home made or custom doesn't matter if nine or twelve port of you could post photos or sizes or both would be great
Thanks ed

Hello Ed,

 

Get a picture, place it on a Graph Grid plus Ruler in Windows Paint,

 

then make it full screen in size, then print screen,

 

open paint again, paste print/screen in and save.

 

 

Now you have a graph to work with, as the Holden 6 manifold is 650mm wide.  B)

 Is this the sort of thing that your looking for.

These are 1.5" primary 28" long, 2.25" secondary 19" long , they suit the 248° cam that I was using at the time.
