Led astray by mistake in Service Manual The sprocket diagram on page 6-374 of the 2002 Camaro Firebird Service Manual is incorrect. The configuration depicted is not possible. The question is whether the cam sprocket dot should be at 6 o'clock or whether the cam index pin should be at 9 o'clock. I had been assuming that cylinder #1 TDC at dot-to-dot (Cam dot at 6 o'clock) is the end of the compression stroke. I therefore concluded that the cam dot should be at 6 o'clock in the diagram. This led to much confusion while installing my rocker arms. It took me less than twelve hours to realize that the dot-to-dot position places cylinder #1 at the end of the exhaust stroke and that the error in the diagram is that the cam pattern should be rotated 180 degrees. Clockwise or counter clockwise, take your pick.
