460 Lower Intake Manifold Question
A question regarding a pair of 460 lower intake manifolds.....Other than the casting year, can someone tell me the difference between an RF-F2TE-9K461-BA lower intake manifold and an RF-E7TE-9K461-B6G lower intake manifold? The top side layout looks the same to me. I'm wondering if there were changes introduced into the F2TE manifold. Any insight is appreciated!
