Brainstormin' 440 vs 5.9 ...

The way I see it, either way 5.9l VS 440 is you need more cam then where you're at now and some head work couldn't hurt, so basically it down to which you would rather run I don't see a low cr 440 having a huge advantage.

Here's a crate 5.9l as you can see for the extra 80 Cid you're not really gaining much Torque wise, a little more head flow should wake a similar 5.9l up but also do similar to the 440, dealers choice :)
