Default Re: "Single plenum" 8ba intake

Anybody ever try this on a factory 8ba manifold? Seems like it should work but I'm not super familiar with how the 8ba works. I may pick up a spare manifold and get down to business
Before getting carried away with hacking up the manifold, remember that the 1932 V8 was 65 HP and had a single plane manifold. With the dual plane manifold in 1934, HP went to 85. Backyard engineering sometimes (oftentimes?) ends up with a worse result.
