are these for the big block or small block

Can't say for sure but it they are for a small block the rubber section might be set 180 off from the "solid steel" engine mount.

Here's a picture of a 340 passenger side.

Look rather like big block to me.

looks like BB but the steel parts are very similar to SB

so they are the big clock one then or is the rubber the big block i have both small and big block this is the resaon why i am asking
