Flywheel Ring Gear
For a 1970, 350/350 with a 4spd, how many teeth should the flywheel ring gear have, and where is the best place to purchase a ring gear?
Thanks.
Thanks.

the ring gear teeth just have to line up with the starter teeth....most have 168 teeth. you can get them from summit...from memory i think the two choices are 153 or 168. and i think my mini starter would drive etiher....
are you installing this or is the machine shop? maybe let the machine shop source it and mill the fly wheel while its there, that way its a guaranteed correct fit

Are you saying that you have the flywheel off the car, and it has 168 teeth? What diameter is the flywheel? And what diameter is the clutch disk? The 153 tooth flywheel takes a clutch disk that is 10.4" in diameter. The 168 tooth flywheel takes a clutch disk that is 11" in diameter.
I'm also not sure why you want to just replace the ring gear. Why not just get a new flywheel? Once you get the new ring on the old flywheel and get it resurfaced, you're probably not money ahead.

If your current 168 toother works it is correct for your application... why would you question what is currently working in the car? Just like refrigerators, microwaves and the like; there are probably not too many actual ring gear manufacturers out there... most are likely sourced from the same factory so buy the best deal. Ring gears are easy to replace yourself... simply cut the old one off with a die grinder, heat the replacement evenly with a torch until it just starts to turn a "straw" color and drop it in place. Might need a bit of push from a brass hammer to seat fully, but it really is that simple a task.

There is nothng wrong with the flywheel and it worked well with the clutch, very smooth. Why spend more money on a new flywheel when I can replace the ring gear myself for so much less. I have already cut the old ring gear off the flywheel and as mentioned above by Markids77, it should be a snap to put the new one on.
