Counting the teeth sounds like a good way.

Will any Chevy starter fit both 168 and 153 tooth flywheels?
No. Chevy uses a number of different noses for their starters. The size of the flywheel and year and model of engine determine what nose is needed. The 153 tooth flywheel is smaller in diamaiater than the 168 tooth flywheel. If you want to use a starter from a 168 tooth flywheel on a 153 tooth flywheel the nose from the smaller flywheel starter will have to be exchanged onto the larger flywheel prior to using it.
Could the wrong flywheel make the starter not work?
yes. a starter made for the 168 tooth flywheel would not engage a 153 tooth flywheel.
How many different tooth numbers are there for a Chevy 350 flywheel?
Theres 153 and 168 tooth flywheels. Are there anymore?
Are the starter drive gears different for the 168 and the 153 tooth flywheel?
The gear is the same, but the nose cone is different.
How many teeth on a 1970 Chevy Camaro 350 fly wheel?
Either 153 or 168. If it has an automatic transmission, it's 153. If it's a manual transmission, it will have 153 for the 1.5" clutch and 168 for the 11" clutch. An easy way to tell is the starter bolts. If both bolts are the same distance from the starter nose, it's a 153 tooth flywheel. If the starter bolts are staggered diagonally from the starter nose (one is farther from the nose than the other) you have the bigger 168 tooth flywheel.
What is the difference between a Chevy 168 tooth flywheel an a 153 toothed flywheel?
Just as the name implies the 168 tooth flywheel has 168 tooth ring gear and the 153 tooth flywheel has 153 teeth on it's ring gear. In the "old days" of high performance the manual 4 speed transmissions allowed a larger diameter 11" clutch to be used with the higher performance engines with the larger 168 tooth wheel. In addition to this the larger diamater flywheel gives the starter better mechanical advantage to turn over high compression engines because of the greater number of teeth on the larger ring gears. Chevy uses a number of different starter noses on their starters. This is the aluminum piece that the bendix gear is in at the "business end" of the starter. This nose is the piece that mounts the starter to the block. This nose is the part of the starter that moves the starter motor in closer to the flywheel on the 153 tooth and farther out away from the flywheel on the 168 tooth wheels. I believe the starter motors are mostly the same except for the HD starters which have a longer stator and rotor for the high compression engines of "the old days". These longer starters allowed the starter motors to develop more torque to turn the higher compression engines over to start them.
Will any Chevy bell housing fit a 168 tooth flywheel?
Flywheels are fitted by engine and crankshaft pattern. Not bell housing diameter
What is the difference between a starter for a 307 Chevy and a 350 Chevy?
Some starters are intended for a 153 tooth flywheel, some for a 168 tooth flywheel. Most 307's had 153's, and most 350's had 168's, but you could put a 153 on a 350 or a 168 one a 307. Both engines are internally balanced, so as long as you have the correct starter for the flywheel, it will work. The one other difference between Chevy starters, is the length of the armature. The longer one is heavy duty, the shorter one is standard duty. Either will work as long as it's mated with the right flywheel.
Will a Chevy 350 5 Speed transmission bolt on to a Chevy 250?
Yes it will. Both blocks take the same bellhousings. Now, the 250 might not have the hole tapped for the correct starter for a 168 tooth flywheel, but you can either drill and tap it if necessary, or just use a 153 tooth flywheel and bellhousing.
With the gm 350 transmission flex plates why is there different amount of teeth count 153 or 168?
The 168 tooth flex plate/flywheel is bigger in diameter than the 153 tooth.If your block has 3 bolt holes to mount your starter(mines didn't),you could use either wheel you want.The 168 tooth wheel will need the starter to be mounted in the staggered position.the 153 tooth will need the starter to be mounted inline.
What is a standard flywheel on chev 350 engine 1972 chev nova 153 or 168 teeth?
That depends. If the car is an automatic the flywheel has 153 teeth. With a manual transmission it also has 153 teeth unless the car was equipped with a heavy duty clutch, which WAS optional in the 1972 Nova, but it is pretty rare. Most of the 168 teeth heavy duty clutches were installed behind big blocks. Yours is most likely a 153 tooth. One easy way to check this is looking at the starter bolts. If they are parallel with the flywheel, then it is a 153 teeth flywheel. If they are diagonal with the flywheel, then it is a 168 teeth, which also means that an 11" clutch is most likely installed as well.
What starter is needed for a 350 Chevy engine with casting number 3970010?
Most of those engines were drilled for either starter bolt pattern. What matters is that you get the right starter for the size flywheel you're using. The 153 tooth and the 168 tooth require their own starter nose cone. Except for the aftermarket gear reduction starters which are usually drilled for either flywheel.
