The 440 is cheaper.....BUT, the Hemi is wicked cool. They can be converted to a carb for the price of an intake at $399, carb $550, MSD coil on wire $650 ignition. I am not sure what else is needed, but I am sure I missed a few things like headers and engine mounts,...and of course the SB trans. Its still only 345hp while your 440 should be closer to 500hp and a bunch more torque. Its your call.....But they are cool.
