I got these rockers in a pile of Ford parts and I'm pretty sure they're GM. I either have a full set for a 6 cylinder plus one or I'm short three for an 8 cylinder. Any ideas? Thanks y'all.

 

Iron or aluminum? Can't really tell from the pics. Aftermarket for sure.

 

Crane 44746. Ford rockers.

 

They're aluminum.

 

turbo Buick parts for sure.....

 

Those are either comp or crane. The application depends on the hole size. If it's 7/16 they're for a big block. If they're 5/16 they're for a ford and were probably pedestal mount, but I doubt thats what they are because cranes for ford have a ford part number on them.

I have no idea how someone can't tell if these are steel or aluminum, the shape says aluminum. And the only company that made these with the top not flat were crane and comp. The raised edges on the sides looks like a late 80's design.

 

I remember the early Cranes (80’s) having the “spoiler” look to them on top at the pushrod cup end. Way back in the good ole 5.0 days...
