Ok, its been some time ...but I am back to creating the Intake Manifold for the Ol 332.. Picture 1 was scrapped and we move onto Picture 2 which is almost complete. After a few attempts , and one heck of a lot of homework...here is where I have arrived. I do need to separate the top plate and separate the runners yet. It was easier to fabricate it as one piece to get the geometry right....but I will be separating the runners . My question is ....How should I pull vacuum for ignition advance ? Should I tap into each runner and build a vacuum can with small vacuum line....or pull everything from 1 runner. It gets tougher if add a power brake booster. I am close to getting it finished, so I am down to details.
