I bump the starter at the relay. My race cars are wired in with a button. Wire between the large stud of the relay and the terminal at the yellow wire at the relay. This way the engine won't crank unless its in park or nuetral. Start at #1 in the firing order. Set the intake just as the exhaust opens. Set the exhaust when the intake is just closed. some cams will like the exhaust set slightly sooner such as 3/4 of the way closed. It depends on the ramps. try it both ways to see if there is a change. After a few trys of "bumping the button you will get the feel for it. If you miss just crank it back around.
