This may seem pretty basic but I'm a bit confused. On a SBC standing at the front looking at the cam & crank gears (double roller) the one I'm taking apart has the dot on the cam gear at 6 while the keyway & 0 on the crank gear is approx. 2:00 not 12. This does correspond to where the pointer on the front cover is located & lines right up at 2. But, everything I've read says line up the dots 6 to 12 There is no actual dot on the crank gear, just the 0/keyway! What am I missing???

Al, the key on the crank should be at approx. the 2 o'clock position when lined up correctly. Check the crank gear carefully, some of the markings on the gears are very small or it might be a triangle or small rectangular shape. When the mark on the cam gear is at 6 o'clock and the mark on the crank gear is at 12 o'clock, the engine will be at TDC of the compression stroke on # 6 cyl. This is the correct alignment.

I hope this helps.

It does help, Thanks!! There is a VERY small mark that lines up with the 6o'clock cam mark when the crank keyway/0 is at approx. 2:00 but almost worn off , maybe with to/fro play? Also, I'm assuming that this position leaves the engine 180 degrees out for proper distributor firing at #1 if one wants the rotor facing up front not at the back?

Correct. When the cam and crank are aligned correctly, dots at 6 and 12 respectively, the dist. rotor will be pointing to fire # 6 on the compression stroke.

Thanks again
