tuff decision! i cant decide between a 98 12 valve or a 2004 dually? all i ve owned is a 96 12 valve for ever and i really like the 12 valve, but i still cant decide. iam wondering wich one is the easiest to upgrade and get the most power out of it. i know you can turn up the pump a lil on the 12 valve but i wont to get a lot more horsepower and torque then just that. and i cant decide wich one i should go with and what kind of upgrades would be best. thanks

 

The 12 valve is cheaper.

Take the extra money you saved and throw in a tranny and whatever else you can afford, and then you would be a big dog.

Or you could buy the 24 valve, and be like all of the other 24 valves.

 

Go with the 12v, you'll love it if you build power into it.
