I take it you mean how the timing gear marks line up? The marks are small stamped round indented circles on the outer faces of the gears positioned in line with a gear tooth. If you disassembled the intake and distributor already, you first probably held your finger over number 1 cylinder spark plug hole until it shot out compressed air & the distributor cap rotor was facing number one pick-up, but when you got the timing gear cover off, you saw the mark on the crankshaft gear at the top of the gear as well as on the camshaft gear. That's because on the typical Chevy small block the timing gear marks are lined up right next to each other when number 1 cylinder is at the top of the EXHAUST stroke, not at the top of the compression stroke, as you would think. No big deal. The crankshaft turns twice for every one camshaft rotation. Just roll the motor clockwise either with a remote starter switch, or temporarily place the harmonic balancer back on the crank, & with all the spark plugs out, roll the engine by hand until the timing gear marks come around right next to each other (camshaft gear mark at bottom, crankshaft gear mark at the top). Change your gears & chain, & do all the engine work you need to do. Make the distributor the LAST thing you install. You can roll number one piston to the top of the compression stroke again, then drop the distributor in until it seats on top of the intake with the distributor rotor pointing straight forward for number 1 cylinder. Or, if you haven't disturbed the timing position yet, just point the rotor to number 6 cap pickup position as you drop in the distributor. Hope this helps. Denis
There is a mark on the timing chain cover behind the harmonic balancer(behind the crank pulley). The harmonic balancer also has a slot cut in it so that you can line the crank up with the mark on the timing cover. The mark on the timing cover should sit at the 2 o'clock position or the 12 o'clock position. My 96 Chevy 305 is at the 2 o'clock position.
