[QUOTE="tmhutch, post: 9291133, member: 4434"] The LSX's dominate by sheer cubic inches and I have no problem with that. I'm glad Ford is finally stepping up to the plate with the 440 ci capable Boss block, it's about time. But you couldnt be more wrong with this statment: "4v vs 2v makes basically no difference if the airflow is similar". There are huge differences that are determined by not only port velocity but what the port is doing at different stages of the lift cycle, especially low lift numbers under .200. Two ports can look the same on a flowbench and perform completely different. Take a read through the link I posted and you'll see what I'm talking about. Read the section comparing LSX's to DOHC's.
