HEMI Cam information

[Rustyiron]

I was wondering if anyone would have any information on this camshaft? I looked but have not found anything.

Thanks

I have one too, I'll see if I have the cam card. 292 advertised and 470 Lobe lift anyway.

I have the Crane & Cam Dynamics list of lobes.

The only one that comes close is: 292* adv @ 0.020". 260 @ 050; 0.471 lobe lift. Lash is 020. 'Large CID bracket racing engines'. LSA is 106.

In The Crane catalog I have, the “R-292” would be a roller, with the 292 being the duration @.050.
The 4706 is the lobe lift, the -6 the lsa(106).

For example, something from a “recent” Crane catalog:
Part number 669091:
Grind number - R-296/4778-8
Specs are - 328/328 advertised, 296/[email protected], .4778 lobe lift, 108lsa

PR,
What I have is the Crane & Cam Dynamics master lobe specs. The only grind I could find with 292 & 47XX lobe lift is the one in post #3.
Does your catalog have tis specific grind?

It does not.

I also have a version of the Crane master list I found on line a few years ago....... and interestingly it not only doesn’t have the R-292/4706 lobe in it....... it doesn’t have that R-260/47xx in it either.
The master list I’m looking at has them broken up by lobe “family”, and each family has a designator/name.

For example, that R-296/4778 lobe I referenced is part of the “R2” family.

What family is that R-260 lobe from?

This is kind of interesting.......
I googled “Crane cams r-292/4706, and a page for a 2014 version of the lobe master catalog came up........ but I couldn’t get it to download.
But if you look at the text....... it shows the R-292/4706 as being in that catalog.

Ha!!
Persistence pays off.
Found it.........
The “4706” is it’s own lobe family:

Looks like a new series created after I printed out my list. Surprised at the large lash.
