			I too am planning on doing this swap (don't know when) but I did notice the bore size in my intake is smaller than the 4412 throttle bore. I am going to enlarge the intake bore to match the 4412 throttle bore (if I didn't do this it would be like running a restrictor plate like Nascar has done).
