Default Starter for a 168 tooth vs. Starter for a 153 tooth?

Hi All - I finally dropped my new motor in my 68 on Saturday. When I went to bolt my starter (from the original motor that I believe to be a 153 tooth flywheel) I noticed the bolt holes on the new block were staggered. I transferred the flywheel from my original 327/300 motor on to the new motor. I am told the staggered bolt holes are for starters for the 168 tooth flywheel. It appears my original starter drive gear has ten teeth. Does the starter for the 168 tooth flywheel have more? Can I use the starter for the 168 tooth on the 153 tooth flywheel? If not I am screwed.

Many thanks any input anyone can give me.


Jim

Check your block agian, as I believe most are drilled & tapped for both patterns. You can use the 168 tooth starter with a 153 tooth flywheel as long as you change the nose of the starter to the 153 tooth style (strait across pattern) I believe the noses are avabile from gm still. You can't bolt on the staggered pattern starter & have it work with the 153 tooth flywheel. To sum it up as long as your block has the strait across pattern also you just need a 153 tooth style nose. They are easy to change. I'll look & see if I can find the part # & get back to you.

327 engines use the staggered bolt pattern. I found that out when I tried to install a mini starter on my son's T-Bucket. It's a 67 327/300HP engine. I found it was easier to buy a new starter. Found one on EBay (new)for $59.95. It's a delco mini with a 4 to 1 reduction gear. Starts that baby right up and it has over 11 to 1 compression. And yes 327's have the 168 tooth flywheel.

It all hinges on the flywheel. The big flywheel uses the staggered starter nose cone. The small flywheel uses the in-line holes nose cone.

In the original applications, all 327's use the small flywheel. The 350's are "usualy" the bigger flywheel but there are some smaller flywheel 350's. "Most" big blocks use the larger flywheels but there are just a few very high HP big blocks that do use the smaller flywheel. It does get a bit confusing. You can swap setups if the block is drilled for the other starter nose bolt pattern BUT you need to change the whole enchalada including: the starter nose cone, the 2 bolts, the flywheel, the clutch assy, and the bellhousing. You can not mix and match those parts as they work together as a team.

You could use the smaller disk in the bigger pressure plate but that would be more of a racing type mod where you wanted a little bit of slip to control the launch.

The 168 tooth flywheel is larger in diameter than the 153. The pinion gear on the starter has to be postioned further from the centerline of the crank with the bigger flywheel. That's why the two designs have different bolt patterns. They are not interchangeable and the bolt pattern difference is intended to prevent one style from being bolted in place of the other.

Thanks Guys,

So it appears that I can:

1) swap the snout/drive gear
2) Buy a mini starter that has universal bolt patterns (one for staggered or flat style alingment).

Has anyone done either?

any real starter rebuilder should be able to swap your nose...make sure you pay him to install a new bushing...
