The 440-3 was produced by Chrysler Marine & Industrial. Far better than the competition as it is built to a far higher standard. It has a number of unique parts which do not interchange with standard 440s (mainly to do with engine front drive accessories). Best to do a compression test. Champion plugs

The drivetrain is set up to run the engine at just below peak torque at highway cruise. 27-2800-rpm as I recall. It'll do this for a few hundred thousand miles

I'd love to have one again

Be sure to keep the Thermoquad. Rebuild isn't difficult (leave choke strings alone), and it'll help. Except a hard to adapt GM QJet no other carb will give better performance or FE. As above, a TBI unit will help FE, but not deliver the same power at WOT. We used to add A on electric fuel pump near tank, upstream of mech pump to avoid heat soak.

I'd use Rotella T6 5W-40 oil and Baldwin oil filter. Look into the issue of adding zinc to preserve cam lobes.
