All of the Offy Manifolds have very short runner lengths.
They built the manifolds for easy installation.
Manifolds tune by harmonics. 1st harmonic length was long, like the old Chrysler
Cross Ram Intakes. See Picture below.
Other Runner Length manifolds were designed for racing speeds.
The Offy intakes fit that situation but are good because of the Injector Placement options, not the tuned length.
