360 stock intake manifold on a stock 318?

What people fail to understand about this argument is this. Air is not being pushed into the intake port. It is being pulled. That means there will be no ill effects from the port mismatch, because there is a negative pressure at the port from the pistons pulling air into the engine. Air does not somehow mysteriously "pile up" at the intake port at the head, because of a mismatch. This is simply wrong thinking and untrue. It's an old wives tale.
