We've been told a hundred times, "I want to make 700 HP!".... Really? Do you know what you're in for?

This is an approximation of what you'll spend on PARTS ONLY to make a given amount of HP. This does not include labor or parts you can sell to recoup cost, etc.....this is just strait parts to make a truck that is POWERFUL and RELIABLE and can do everything you'd expect to do with a truck.

Remember, there are 3 things you can have when you do a build. You can have it Cheap, Reliable and Powerful.....but, you only get 2 of those at any one time. (i.e. it can be cheap and reliable, but it won't be powerful, etc.)

In the chart below, the yellow, orange and red marks represent a few key spots. These are mainly places that you need to upgrade shafts (i.e. input, intermediate, output). The 600 HP mark is where it gets a LOT more expensive for the Duramax's. This is where the motor needs to come out and rods need to get replaced and you might as well do the whole motor at this point.
