You can get the 450 as a mech. Or vaccum secondarys.You can also change the back half from a mertering plate to a metering block by useing the meter block off a 390 this is what had told me a few yrs back. And if you change over to center hung float bowls you can then have a dual feed instead of the rod the feeds from one bowl to the other.
