Received a set of rocker arms today .FedEx showed up on Sunday. Surprised me .but to the point..
Has anybody here ever seen a set of small block rocker arms as those pictured?. These were sold to me as a kit Made by Crane Cams. The seller whom I consider to be a quality provider of Quality Parts for Chrysler specific vehicles.
This is my first transaction with them. I called them to confirm the application , as well as the availability , because they didn't look like any small block rocker arm I'd ever seen before . And they had been posted on the website for some time as the last available . The part numbers posted at the website match The Crane Cams part numbers . In the last 6 months I've likely looked at thousands of small block rocker arms . I was assured on the telephone that they were small block rocker arms and that as long as I had not bolted them down I'd be able to return them. Gracious and informational and good on the telephone I have no complaints whatsoever other than what I see before me with these rocker arms. If these are small block rocker arms I may piss my self because these would be the best-looking LA arms I've ever seen. The arched rib across the top has got to be strong but I just don't believe they could possibly be that good a deal. Big block I say, how about you?
Thanks all .
I'll be on the telephone tomorrow morning . Hopefully a video call and I'll set these things up on a cylinder head I have mocked up here .
Matching them up side with an original rocker through there packaging has offered no definite that I can identify.

I agree we could use a better pic. They look like Big Block arms. Measure the shaft length. The springs are also from that set up , small blocks use spacers unless this kit is different.
 
I'm trying to get some time in here to get to the factory service manual to see if there's a dimension I can get. from Center of the shaft to the pad or the adjuster or Center to center of pad to adjuster.
 
The shaft bore through the rocker seems to be the same width as a 273. But the link from adjuster to the pad that difficult to tell without breaking Packaging and I don't want to get burned for cost on this so I'm reluctant to break the packaging until I have them on the telephone
 
I think the retailer put this kit together not crane. They couldn't tell me if the shafts were grooved or not. I was told likely they were not grooved shafts. The shaft length is small block
 
Those look like big block rockers by looking at the pushrod adjuster location which seem to be a little off center. Small block adjusters are centered in the rocker.

The small block Crane iron rocker kits did come with springs and not spacers. The shafts were not grooved in the Crane small block kit. I have a couple of pictures of Crane small block rockers. I am posting one or two on my phone but may have more at home. Ignore the shafts in The background as they are not Crane shafts.

Crane in third picture is one on the left.

The rockers are offset. They’re for a BB.
SB rockers are straight(all 16 the same, no lefts/rights).

The SB Crane rockers don’t really look anything like that.
They’re more like 273 rockers, but “beefier”.

Edit, I see Rocket has a pic of one above.

The OP may have still done okay with those depending on what he paid for them.
I believe the current price for Crane iron BB rockers and separator springs(no shafts) is about $500.

I one time got a set of Comp LA rockers on RB shafts new from Comp. Anything can happen on the assembly line.
