LS-7's are iron block/heads. The suffix is "XCH". They are hard to identify based off of redily available material, but do have lots of power.
I have one in my '64 chevelle malibu.
casting # on the heads should be 6272990(open chamber rec. port)
"XCH" is stamped on the front on the block.
Iron block and Iron heads.
