factory style piston pin snap rings source?

[dibbons]

I know, spiro locks are better, but what if I want to use the plain old-fashioned, regular snap rings in my circa 1970 full-floating wrist pinned 340? My on-line searches are getting no where. Thank you for a brand/part number/whatever helps find these things (.984" pins).

Can't think of the part number, but Sealed Power still has them. IIRC, they are the same as the BBC snap rings.

I've never had one fail.

Are those doubled on both ends?

Nope. I'm running singles on each end.

If I was going to wind it up, I would have machined the Pistons to take double Tru-Arcs. I'm just not beating on it that hard.

That round wire snap ring won't work in a piston cut to use square style snap rings.

I might just re-use the old ones if it seems so difficult to find, the motor has not been touched in years, so chances are the existing snap rings were USA made, at least.

I should have known perfacar would know the part number. I'd bet a sizable amount he has some on the shelf!!

Thanks perfacar.

Try Sealed Power LR-194. I bought some a couple years ago, I think from Rock Auto.

Any shop that deals with UEM (United Engine and Machine Co.) could help you get this.
