oil drain plug with magnet

[John M.]

I have seen the A head engine oil drain plug with the magnetic tip used on HP solid lifter engines such as 327 340HP, 396 425HP pass car and corvette, and 1966 427 425HP, I have never seen a A head drain plug with a magnet used on a low HP engine..................any thoughts, did all HP engines use them 1963 - 1969 ??????..........Thanks John Meissinger

GM says that the magnetic drain plugs were used for 1965-66 Corvettes with L-76, L-84, L-78, L-72 and, possibly, L-79 as well as 1965-66 passenger cars with L-78 or L-72. Otherwise, I think they were a SERVICE-only item.
