Inliners,
I have had plenty to do in the last few months, but I thought I would update everyone on the progress of this intake I'm building.
The CAD parts are being Laser'd as we speak and I hope to get them in a few days. They nested out pretty well on the sheet. When I get them back I will get them to my buddy who is a wiz in aluminum Tig Welding. I learned a lot about providing him with alignment holes to jig the assembly while welding so everything will be correct. I added a "Tree" to the intake flange part and I will bolt it to a steel plate to assure no warping. After it's all welded, I'll grind off the "Tree". These little details will hopefully get it right the first time. I would have never thought of all the details without my friend's experiance in welding.
I am also rebuilding the 5 Holley 94's at this time. They are not too bad to rebuild, but I am going to add longer throttle shafts and all new jets.
I read an article stating that the total volume of the intake should be divided by the CFM of the carbs to prevent a too rich/lean mixture in the combustion chamber. This will take the longest to get setup correctly. Anyone have a carb sync tool I could borrow? Since I am going to block off the 2 intermediate carbs (numbers 2 & 4)with a solid gasket, I will only have to sync the two outer and middle carbs.
Please see the following photos. I'll keep everyone posted when I get the parts back and welded up.

What it might end up looking like when it's done. I'm not sure it's the look I was looking for on the old Coupe. I think it will look better on the new RatRod
