Mike B - Good catch sir! My mistake in saying the 1960 235 was in a '52 (mikeg1955 said something about owning a 1952 Chevy which I mistook for the truck being discussed) - duh. I see now that the '60 235 is in his "1955 second series 3200". It sounds like it was installed using the 1960 style mount, but no way to confirm without some pictures from mikeg1955.
That being said, I think you are correct in that he can use the Task Force style "birds legs" front engine mounts as long a the 1960 235 has the mount bosses on the block. He could eliminate the 1960 style single center front mount then.
Perhaps mikeg1955 could post some pictures of his existing mount and engine so we can be sure we are giving the best correct advice going forward. My apologies for any misunderstandings.
