68 dart small block vs hemi

Well you could always compromise and run an modest, big wedge instead. They're easy to maintain/work on, low mantinence compared to both the 340 and the hemi in any given power range. ie: a 440 making 600hp (lets not mention the natural torque this motor is prone to make) is a joke and will be far easier to maintain than a 340 making this amount of power.and will out peform your current 340.. hands down, when one is right.. my 2c
