Rule of thumb I use is take the price of all your parts and expect labor costs to cost anywhere from 1/3-1/2 the total.All over the place? Back to my first post I wanted to know what parts other than block and HCI would be needed for a build and how much I might have to pay to have a motor built and put in my car. Nothing about what suspension would cost, only what you would upgrade. Nothing about making 500 hp. I can't make a budget without figuring in what labor might cost. It's the beginning of a plan, so I'm not worried about technical parts and all the manufacturers. Any clearer?
