273 Intake Manifold Question!
Keep in mind Offenhauser is still in business. I have an Offy dual quad #5488 intake that is designed for smaller port 273/318.
The chaos here is definitely perceived. All the OP is doing is carrying stuff good lord. No need for the over nodding. With all the other mods here, I next to never see them "reprimand/delete/edit".
Reminds me of a make work project....
