You Can't Tune a Summer Breeze


In the early '60s when air flow benches were emerging in the performance and racing engine building sector, the credo was "more air is more power."

Stock (or near stock) cylinder heads and intake manifolds were typically restrictive to air flow in the above-5000 rpm range, never having been intended to make power at this level of engine speed. Cylinder head "porters" simply made passages "bigger" and the path to high performance intake manifolds was pretty much the same.

Problem was, "how big is big" reared its head and these same proponents of larger flow passages discovered that more air flow wasn't always more power.

Also contains plans and a build list for those who wish to build their own bench.
