Wrong. This manifold is great for what it was designed to do. This manifold is designed primarily for increased bottom end torque while still improving mid-range and top end power. The single port is designed for increased mid-range and top end performance with a significant sacrifice of bottom end torque. People have a tendency to over carb their engines, this dual plane will not perform well with more than a 450 cfm carb. To preserve the high bottom end torque on my 300, I ended up using a Holley 390 cfm.
Offenhauser makes good stuff; hope it does what you need.
Agreed, plus Offy stuff always looks "classy" if ya know what I mean.
Love your plans and overall approach for the engine ! It should do quite well !
I've ran one of those manifolds round off the end of the port seperater it helps flow alot
The open version of this intake is a nice piece. The dual port sucks balls. Anything Offy Dual Port is a major power killer.

Ah how plans change 🤣
Therez a ford maverick withba turbo 300 out there on youtube that is apocalyptic fast. Them 4.9 motors can boogie with the right science applied.
