Here is what my cognitive fermentation came up with for the Weber/Holbay manifold to Weber/Alpine modification.
Left standard Zenith downdraft manifold Right Weber/Holbay manifold ---- Top - Bottom respectively
The runner length measurements (67mm) are exactly the same as are the thickness (7mm) of the manifold to block faces.
Weber/Holbay ---------------------------------------------- Standard downdraft Zenith
This is what I originally thought may be the case. Thus, I plan to cut each at the 67 mm line and Tig weld back together with a 5 degree upward direction. This should provide clearance for the Webers in relation to the inner fender surfaces. What also appears to be an advantage, the 33mm inside continuous orifice diameter of the standard Zenith manifold will be replicated to the Weber/Alpine setup. My manifold port and polish process has the head intake orifice at 30mm from the standard 28mm. I could make it 33mm. Any thoughts are welcomed.
