A couple of sites to check would be Holley.com, edelbrock.com,
force-efi.com    I found a bunch with search engines and a little
patience.

A cam with too much duration does not produce adiquate vacuum at idle. 
The MAP (manifold absolute pressure) sensor will read low vac. at Idle
(thinking there is a load on the engine) and increase injector pulse
width.  Basically dump fuel @ idle.  That is the main reason I know.  If
you find out another, let me know.

Just an Idea:  if the 440 has the same intake bolt pattern as a
currently fuel injected mopar (I don't know) you may be able to
fabricate your own custom system with mopar and aftermarket parts.  It
would probably be expensive, but might be worth the effort.
