Are these Big block perches?

I pulled these out of a frame I got and don't know what mototr was in it. I think they are the same as the ones I pulled froma burb with a 454, but want to be sure before I post them for sail with bad info.

Re: Are these Big block perches?

I thought that BBC perches were made wider so that the motor would line up the same with the transmission?

the bbc and sbc line up exactly the same. the 68-72 used a different perch for exhaust clearance
later model trucks used a mount that will clear either engine
