This is a subreddit for asking Mechanical questions pertaining to vehicles, engines, etc. Just order a balancer for a late-70s era 350 Camaro engine and it'll have the mark in the right postion to work with a 1:30 position timing tab.
If the old cam gear was aluminum with nylon coating on the teeth the mark on the upper cam gear will be a little arrow pointing inward, if you're replacing it forget the nylon gear and don't let anyone sell you one, get a steel or iron replacement upper gear or buy a timing chain set that comes with steel gears.

The crank key-way will be at about 2 O'clock when the timing mark is pointing straight up. Adjust the timing, if necessary. This is normal, because ignition works on a curve, allowing for the speed increase and adjusting the timing accordingly. The small block Chevy 305 engine was introduced in 1976 as a fuel economy engine. Not the most precise way to do it, but it works. There my be several other ways to loosen the distributor clamp but this one worked for me.
Please read the on the subject for details. Dealer, Salvage Yard, Google Search. I ran mine with a no vacuum advance unilite 36 degrees in by 3000, 38 degrees on race gas. To adjust your timing, all you need to do is turn the distributor housing one direction or the other, depending on whether or not you want to advance or move back the timing. You then need to find to advance wire for the distributor and disconnect it. Modern cars that are controlled by electronic ignitions don't need to have their timing adjusted, but old-style 4-stroke engines require that the timing be adjusted periodically to optimize the efficiency of the engine, making sure that the spark fires at the appropriate moment in the ignition cycle. After it is set tighten down the distributor hold down bolt.
Other wise you will bring in the vaccuum, which would activate the centrifical. Attach the power wires from the timing light to the battery with the black wire clipped to the negative cable and the red wire clipped to the positive cable. Rotate the crank until the marks are where then are supposed to be. The timing tab on my vortec is molded into the timing cover which makes it impossible to see from the traditional slight high side view. Those who demonstrate they cannot follow the rules will be warned and posts removed. A regular old stamped steel cover should fit, although you will have to remove the crank sensor wheel and add the 2 alignment dowels that an older tin cover lines up on the holes are already there, just need to tap the dowels in.
I pulled the distributor up and moved it a tooth and put it right on the money. Good Luck here the best answer i can give you on the timing of a 305 Chevy engine i seen timing on these engines from 0 to 13 btdc the best way to set the timing is to disconnect the est plug and start the enginge and very slowly turn the dis.

Once that's loose, just rotate the distributor until the timing mark is in the right position and then re-tighten the bolt. I have no idea what the 1 spark plug tower is. It is a big weatherpack connector, you can hardly overlook it. With a stock camshaft you shouldn't have a problem but if an aftermarket cam with more lift was ever installed then the valves should be backed off before turning it over like this as the valves could hit pistons depending on the position of the crank, although if the timing chain jumped on an engine with a big cam then the damage has probably already been done anyway. This is a zero tolerance policy.
When you pull the distributor the rotor will turn counter clock wise, try and remember the place, also, look at the cap hold down screw and try to remember it's location. Over time, this tends to get misaligned somewhat, resulting in a less-than-optimum spark plug firing time. Mark the spot on the harmonic balancer. The harmonic balancer is the round disc-like part that the crankshaft pulley bolts to. The reality is a little more complex. Grandmother's old car with 33K original miles. That will make it easier to get the initial timing.
The Vs are upside down when you look at them from the front of the car. Or search —someone has likely run into the exact same problem and is likely willing to share photos and advice with you. It won't make it unbalanced on a 350 or 305 internally balanced , but only on a 400 externally balanced. Hook up your timing light or timing gun. In order toadjust timing, you must move the distributor back and forth afterloosing the retaining nut for it. The timing of the ignition refers to the point between the compression and the power strokes at which the spark plug fires, creating the combustion that results in your horsepower, forcing the piston down into the cylinder.
