We sell a product. We use the profits from our products to continue to develop new products. When an customer pays for our product, they are paying for knowledge that others probably don’t have. So when you ask for free advice about building your engine, it is an insult to my customers who have already paid for it. Similarly, if you ask me what camshaft you should put in your father’s tow truck, I’m probably not going to respond. The only information I choose to openly share is on my Frequently Asked Questions page. If it isn’t on there, you are probably out of luck. Feel free to spend your time researching the same things I have for the past 15 years to get your answers.
