Re: 396 427 454 nos rocker arms ls6 copo
Im puzzled on this one..its like the z/28 0 rockers...they were small 0..large 0..sideways 0..but..the original gm parts book says 65 to 70 hi-perf big block stamped with a H on the tip...Ive taken apart too many original big blocks to count and found both rockers..I thought the L was a newer issue..
