Ok so after looking through the thread on the 1050 engine it seems like getting all the bits together to make it happen might be a pain in the butt. So with that in mind I'm thinking about just boring out the cylinders. Then I remembered tale about PBS heads. As I understand it they are still available from a new vendor. What's the deal with them? Are they streetable? Do I *need* a crazy cam to see an increase an power? Or is just that a crazy cam will help me make the most power out of one of those? My goal is to make enough power for daily driving. I was hoping to hit 70-75hp and keep things reliable.
