Can anybody here tell Me what kind of Rocker Arms I have in My recently built 454 in My 1970 Nova SS. I have never seen Rocker Arms like this before and am sure they are not stock 454 parts.

Look like maybe Ford 351 Cleveland/351M/400 with a aftermarket roller trunnion upgrade.. Their 1.73 ratio is very close to the same, often BBC roller rockers were used on Cleveland Ford and Ford 429-460 back when performance parts were not very plentiful for those engines...but I've never seen someone do the opposite and use the Ford parts on a Chevy.

Just a educated guess.

Thanks Guys, maybe that they are Ford parts is why My interweb searches for Chevy Big Block upgrades has given Me no results.
