There is supposed to be a tab on the timing cover a lot of times it gets broken off. GoodluckJoe
I have a 1986 Suburban with a 350.More than likely it's in the same place as mine. Look behind the water pump from above, more than likely your TVS switch will be in your way. However, it is there. The vibration dampner will identify TDC almost completely verticle.Behind the pump you should find a traditional timing gauge along with a tube extending upwards through the gap between the water pump and block. It is possible to set the timing to this mark, however like mine, you may have to remove the water pump to clean and verify it's accuracy with alittle tweak or Two. The tube is for a special kind of timing indicator/light for the shop tech to use. I know, it is seems like a dumb idea compared to the traditional timing mark between the power-steering pump and bottom of the water-pump, but what can you do, it was the 80's.
If you are having trouble seeing the timing marks spray carb cleaner or Brake clean on it till it cleans up. I have also pushed a rag down on it with a long screwdriver and wiped it off as well.Stan

How can you distinguish between a Chevy 350 and a Chevy 305?
The easiest way is to look at the Harmonic Balancer. The 305 has a wider thicker balancer than the 350. Pus the timing tab on a 305 is located ON the timing cover and the 350 is bolted on the with the cover bolts. Riky9
Where are the timing marks on a 1986 Chevy truck 305 Mine has no markings or indicators?
The only thing I can think of is that the timing tab on your engine has been removed. The hash mark should still be on the balancer, but may be obscured by dirt, grease, or accessories. You might be able to get a new timing tab from an auto parts store or dealer. Some professional quality timing lights have a timing readout, which would eliminate the need for direct reading.

Where is the timing tab located on a Chevy 305 high out put?
Make sure that the number 1 piston is at TDC (all the way up with the intake and exhause rockers loose). The camshaft and crankshaft gears (timing chain gears) have tiny notches imprinted on them that would face each other when the engine is timed right. ie. the crankshaft would point directly up, the camshaft would point directly down. The timing tab is welded to the timing chain cover at the 12:00 postion.
Set timing on class a motorhome chev 454 1986 there is two timing marks?
I believe what you're talking about is that there is two timing tabs on the motor. One at 1 o'clock and 1 at 5 o'clock. The top one is hard to see so gm put one on the bottom where it is easier to get to or see. If you use the top tab you hook your timing light to the #1 plug wire and if you use the bottom tab you hook to the #5 wire

How do you find top dead center on a GM 305 engine?
Remove the #1 spark plug, hold your finger over the hole, and rotate the engine forward by hand until you feel compression coming out the hole. At this point the timing mark will be approaching the timing tab. Align the mark with 0 and you're close enough for most things except a degree wheel.
Timing marks on 5.7 Chevrolet C1500 1994?
The timing marks are on a metal tab just above the Harmonic Balancer. The triangle on the drivers side is 0 deg. With a timing light it should be set with the line on the HB lined up on the 0 deg mark on the tab each time the timing light strobe fires. This is all done with the tan wire with the black stripe (timing set wire) un hooked. Hope this helps.
Where is the timing tab located on Chevy 350?
it should be just to the right(if your facing the engine) of the water pump attached to the timing chain cover, real close to the harmonic balancer if it is a truck your working one it is hard to see and get a timing light close to because of the a/c compressor and the power steering pump belt i just retimed my 85 c-10 and i removed the fan a/c compressor and the power steering pump so i counld get the correct angle to the tab on my truck i could not read the marks anymore so i put a new tab on my you can get them at autozone or napa they should stock them and they install using two of the timing chain cover bolts but then you also have to find your TDC on you number one cylinder and mark it a zero on the timing tab or buy some timing tape and put it on the balancer at TDC
Where are timing marks located on a Chevy Small Block?
The timing tab will be drivers side, right abover the bottom pulley. The dampner will have a slot cut accross it's surface. Via strobe, or timing light, these two will line up.
How do you adjust timing on a 1976 350?
Disconnect the vacuum advance hose from the distributor and plug it. Make a white or yellow mark on the harmonic balancer at the 0 degree mark, and a mental note of the numbers on the timing tab. Connect a timing light to the #1 ignition wire and start the engine. Aim the timing light at the timing tab and observe where the white or yellow mark aligns on the timing tab. Loosen the distributor hold-down clamp and rotate the distributor to achieve the desired timing. Most '76 model 350's had very low compression from the factory, and benefit greatly from increased advance. The factory settings were probably around 6 or 8 BTDC but they can be set up to 16 BTDC depending on fuel quality. It would be unwise to advance the timing to a point that caused pinging under part-throttle, as this could easily result in broken pistons. Reconnect the vacuum hose when finished.
How do you time a 1974 350 Chevrolet?
Plug the vacuum line to the distributor. Run the engine while pointing a timing light at the timing cover mark. Timing light should be connected to #1 plug wire. Turn distributor until the timing mark on the balancer lines up with the #8 on the timing tab. This is a good staring point. Most will take about 12 degrees.
