This would make it bad *** -

and the Flex-a-lite 295 fans can be used with the big radiator -

The install was a little cleaner when I was done
Besides these mods you can also go with aftermarket headers, intakes, programming, catbacks, cams ect... There are quite a few options available. We have a seperate section of the 8.1 trucks on our website.
Hope thlps helps,

you have all the right ideas, just do it! computer tuning will do more for it for your dollar than anything else. the flex-a-lite 282 fans tbyrne shows would be a direct fit for you if it has the 34" radiator like the 6.0's.

Spend your first hard earned money on good 4 into 1 equal length headers and a good cat back system. After that a good cam and computer reprogram will give you the best bang for your buck! The engines a fuel burning air pump, you can try to add air on the front end, but if you don't get it out smoothly on the back side you won't find your Bad *** power!
