Diesel Bombers - New to site.....

Been lurking a while, decided to join. I just picked up another diesel truck, and I am wanting to do some minor mods to it. Just looking for more pulling power, nothin crazy, just a bit better. Current lineup includes;

1997 Ford F-250 Heavy Duty 4 door - 7.3 Powerstroke Automatic (NEWEST)
1994 Ford F-350 Crew truck 4 door flatbed/toolboxes/rack - 7.3 IDI 5 Speed (non Turbo)
1990 Ford SUPERDUTY 2 door with flatbed - 7.3 IDI Automatic (non Turbo)
Wifes ride 2006 Dodge Durango - 5.7 HEMI Automatic (turbo???? Good Idea!!!):rocking:

I own a steel fabrication business, and a few weeks ago my crew blew up the 7.3IDI:argh: in the 350, so for a quick fix I put the motor from the SD in it. The block from the 350 in at the machine shop, and will get a complete rebuild. I already bought new heads, so the new motor should be good for another 500k.

The 250 is my daily driver/hauling truck, and the one I am looking to mod. As far as I know it is completely stock except for the air cleaner. So any ides/thoughts/suggestions are greatly appreciated.
