[kji420]

so i went to look and see what engine i have in my 87 lx4dr, thinking it would b a a20a1 but no, its a BS, no, im not kidding. instead of there being the normal a20a1 stamp, the only stamp is BS with the serial # under it. i tried searching but ended up not finding anything.
so if anyone can help, please do thanks.
