1970 Harrison radiator tag

[D S.]

Found one on a friend's 1970 LS-5 with automatic and AC radiator that has a large MH and a small 9. Does that MH9 have any meaning?

Thanks,

Scott,

It does. My '71 LS6's have MJ9 tags.

It's the radiator broadcast code. I have one on my 69. Don't remember the characters.

Manual vs. automatic. Big block vs. small block. Various horsepower configurations within the BB/SB designation.

They clip onto the side tank. Mine is on the passenger side.

Chuck is exactly right.
