Okay, better question. Where are you wanting to pull? Who put's that pull on?
We gotta start with the rules, otherwise you are just building a truck to pull for exibition only. I'm not trying to overwhelm you with questions. Power Stroke pullers are rare for a reason. They are hard to make power with, and they are expensive. But with the right information, and people to work with, you can go out there and have as much fun as any Cummins or Duramax. Sure, you may not win much, but fun is the goal. At least it is for me. I'm a die hard Ford man, but love to work on all of the above. I just like to build things that people say "you can't". Which is the case alot of times with a Ford.
So ya gotta be honest with yourself. If this truck is your daily driver, are you ready to commit it to the track? Do you have another truck or car to drive? Are you self sustaining, i.e. have shop or place to work with tools? Or do you just want to pull once or twice a year at a county event, then drive the truck the rest of the time.
Like I said, I'm not trying to scare you off. I just know that information about hard core Power Stroke stuff is tough to come by for the new guys. And alot of times, the BS from the "Power Stroke know it alls" plus heat from the Cummins/Duramax guys can cause you to not want to see your project throught. I've been there. The true enthusiests of diesel will always help you out with info no matter what make their alligence is to. So I want you to know, I'm here to help. And by no means am I the "End All" information source for Power Strokes. But you asked about building a puller only with a Stroke, and that's exactly what I'm doing right now. So it's all fresh on my mind. Not to mention, I'm VERY excited about it.....if you can't tell. LOL
