LT1 Rocker arms
 

Did the 70 Z28 use the "O" rocker arms? Thanks...Tony

Tony I am pretty sure the hi perf "0" stamped rockers were used on LT-1s. I recently found one in my old tool box. All the parts in there are from my brothers 1971 Z.

Well I kinda thought that someone else would offer an opinion. Darren, I appreciate your response. I will find a book that has the info. Nice to be a "member".

I might be able to add a little more info.
Rocker Arm unit #3843359 stamped "O" on the inside of the pad end,& in 1970 changed to Part #3974290 also stamped "O" was used on:
*1962-69 all 8 cyl,(exc. 396-409-427).
*1970 all 302-307-350,& 400 w/2BC
So Yes,the 70-Z28 would have used these rocker arms.
