Good mods to make torque in a 440

If your closed chamber heads don't require excessive money put in them you could utilize the extra compression point.
When it comes to dual plane intake manifolds
most go for the newer edelbrock RPM or the CH4B for a nostalgic choice.
The 440 is a torque engine by design. Good
assembly practices and you will have this one
spinning the tires on your Belvedere without
really trying.
