I think that would be a nice home for a mild 440, especially since it would make best under 3,000 rpm power.
Where the 5.9l can make similar above 3,000 rpm power and torque than a low cr 440, which is where your mainly gonna be At on the track. With the right cam and heads, ported and or aftermarket the 5.9l can make all the power you would really be interested in.
