This was my first time using White Performance & Machine Company. They put together a custom engine based on my needs. They pointed me in the right direction as far as what I needed, and they were very knowledgeable about the best motor for the amount of money I needed to spend. One of the features of the package I purchased is that instead of just providing a final sheet with all the engine specs at the end, they provided me with a video explaining everything about the engine, and I can see it all on video. They make each video specifically for each unique customer. It shows the actual engine with the name written on side of it. A lot of people just tell you how much horsepower the engine has, but to see it live on video is pretty incredible. You can see that you are getting exactly what you ask for, and it comes in handy when selling the engine because you can provide concrete evidence that the engine is what you say it is!
