Yeah, one of my favorite sayings is, " The only difference between a scientist and a hillbilly is a scientist a has do***entation on his last geuss"
I have few. There was a good article 40 years ago about the factory Ford Ranger Baja 1000 trucks running modified stock manifolds instead of the Offy because they said it ran better. So its more about looking at characteristics of the two manifolds when we kind of have the answer about which one ran better. The Offenhauser makes more than the Ford 2 barrel manifold stock. The floor design of the Ford manifold is better, which leads to better fuel distribution. Once you make it a 4 barrel to improve the airflow, you've now created a good flowing manifold with good fuel distribution.
