WIW Early BB Adjustable Rocker Arms

[440Coronet500]

I have a set of what I believe are early Chrysler OEM adjustable ductile iron rocker arms. The only identifying markings on the rockers are E6263M. They have the drilled oil holes that direct oil to the tip of the adjusters. Can someone please confirm what these are and ballpark value? 440'

Some of the early aftermarket were not marked - isky for example. I have a set of blanky isky and a set of crane with the name on them.
I've had a set of stock max wedge rockers moons ago. Didn't have those numbers as I recall.

Im assuming you have googled the numbers?

Prices vary. I just bought my cranes for $225 shipped to my door with a set of used 440 push rods. My isky set I bought a decade ago for $100.

Edit: you will see similar iron rockers on eBay for $400 a set or so that never sell.

Those are OE rockers.... I'd rather have those than 99% of the aftermarket arms currently on the market.... Iskys are better but no longer being made/sold... Crane Ductile rockers are about equal to the OE rockers...

I'll buy all the Iskys I can find at $100 for a set.. Those I wouldn't part with for less than $250....

The last set of OE rockers like that that I bought were $150, but that was many moons ago. I now have them installed on a 451 stroker with a sixpack.

That Dart is probably adequately powered.

They sure appear to OEM rockers. All my Isky rockers had a hard steel tip. They're not Cranes either as far as can tell, all the Cranes I've have Crane molded in. Only the OEM Mopar looked like a Crane as I recall.
