Hi guys. My name is Doug, I live in Innisfail, Alberta, Canada. I have a 93 D250. so far not much for engine upgrades, as I don't know lots about them. just cold air, 5" stacks, and that's about it. the truck it's self has a lift with 35's. Would like to get about 400 HP out of it. Any info would be great! He's a pic of my baby
