After the TDC point, you need to adjust the timing by turning the camshaft sprocket in both directions. Rotate it in a clockwise direction to generate more power from the engine.

The stock setting is 6 degrees Before Top Dead Center (BTDC). Each little line on the timing tab should equate to 2 degrees. If the timing needs adjustment, I walk to the passenger side of the engine and loosen the bolt that secures the distributor to the intake manifold (you have to access it from the passenger side).The engine is a 290-horsepower Chevy crate engine with a set of headers, a Holley dual plane intake, a 750 Holley 0-3310C Holley carburetor, and an MSD Ready-to-Run distributor with a matching coil.
