I didn't post in this thread to be a jerk, but when people who know better blow off facts or another's factual points...why should I not do the same in return. Exactly what facts of YOURS did I blow off?
Do you believe the factory magnum int port has an advantage over the old 360 port? In fact yes. You are missing the much better short side radius, deep bowls, better pressure recovery design of the chamber and the superior exhaust port design.
I believe on a 318 magnum is that in the middle better choice for a street car needing a lil more power but isn't looking for or all out.
But the 318 port is 125 and this magnum is 153 cc, so whats 7 cc?lol ???
I agree with you also on intake manifold runners and sizing for ...air speed and the response/torque from it.
