PISTON RING SHAPE (Samll Block 318 2bbl)

[yxkullsgatan]

Hello guys

I'm looking for a piston ring set for my 73 dodge charger 318 2bbl but there are some differents "teeth shapes", I already ordered twice at Rockauto and each time there are wrong pistons rings although it was for 318 2bbl 73 Dodge Charger, I'm looking for those one, this specific "teeth shape" on the last pic you can see what I revceived from rockauto, we can't put it on the piston

It appears that the expander with an internal "key" is intended for ring grooves that have holes drilled for the key. This positions the expander and prevents it from spinning.

@John_KUNKEL Hey Thanks so lot for your reply once again !

But do you know where can I buy some ? I've been searching for a lots of sites and it's impossible to know if there are those specifics "teeth" on the the ring, like you said with the internal key.

I do need those piston rings, that's the last part we need to finish the engine, i'm desesperate for help !!!

You could just snip the key off if all the other dimensions are correct.

@John_Kunkel Thanks again for your reply.

To snip the key off is a bit risky, because they're probably going to spin...Maybe it won't be blocked as it should be. I'm going to keep on searching this model I need, I'm sure it exists...

Don't hesitate if you find them to let me know !

Thanks guys.
