Technical I need some help IDing a Weber flywheel

Hey guys, I have a Weber flywheel Im looking to rehome, but Im not sure what it fits.
Anyone recognize this ?
Thanks

 

Hemi, couldn't say which though, @73RR would more than likely be able to tell you

 

Looked at my Weber listing and don't see any with 143 teeth...are you sure about that? Should be stamped into the side of the ring gear..

 

I'd guess 1968-69 Big Block Mopar.

 

Looks like an early hemi because it registers on the outside of the crank and has 8 bolts....Just a guess...

 

Ok so I just recounted again, and Im still getting 143 teeth.
284321 is all I can see on the ring gear

 

Im sure, and thanks for taking the time to look in you.

 

looks like you can find a few 8 bolt 143 tooth Mopar flywheels at summit, etc. Says they fit 1963-1971 Hemi mostly.

 

The 143 t gear looks to be an anomaly, perhaps a special order?
Get out your calipers, the early flange is 4.811" OD and has 8 bolts on a 3.937" b.c.
One hole is offset by 4 degrees.

 

And information I’ve seen says the 143 tooth f/w fits the Mopar cast iron bell while the 130 tooth uses the aluminum ‘513 bell housing. The starters are the same for both.

 

The 143 and 130 definitely use different bells due to the huge difference in od.
Just another oddity from MaMopar, the post 62 143 tooth count is about 0.050" smaller in gross od than the 146 so why did they screw with it?
Also keep in mind that the 143 was first used with the 426 and it was a cast iron bell then resurrected for use with the 4-spd od in late 70's-80's and an aluminum bell on the LA engines.

 

I put a 143 tooth ring gear on a 146 tooth fly wheel and to my surprise the inside diameter was the same. The 143 gear was for a V6 94 Dakota.
