    They are for BBF.

    They say 460B and 1.73 on top, CAT on the bottom.

    Not sure what brand they are.

    Anybody know?

    Cool

    Maybe they're CAT rockers. California Auto Transpeed. Personally, I wouldn't run them on a jet boat engine. I've heard of CAT rockers failing too many times in high performance engines. (There are some CAT brand parts I will consider using, but their rocker arms are not yet one of those parts.)

    Don't cheap out on your valve train; get a quality brand-name rocker arm set from an american manufacturer, such as Comp or Scorpion.

    By the way, they also look a lot like the CompCams Pro Magnums, which use a CAST rocker body...and have been known to break. Those CAT rockers look to be cast as well, and if Comp's cast rockers have been known to break, well...

    I used a set of CAT roller tipped rockers on my Chevelle with a very mild 327, ended up chewing the tips off the pushrods. They said they'd take care of it with another set, never came thru. Won't use any of their stuff now.

    Yep, they are CAT extruded aluminum rockers.
    I can't use them on my boat anyway, so I'm getting rid of them.
    I have the lowly D2VE heads. Won't work.

    I had a set of CAT rockers on my Pontiac. They were total cheap Chinese junk. Half the rollers tips were flat spotted after less than 10 hours of run time. Almost all the tips were locked up. They were just the roller tip not the tip and trunnion rollers like you have. I switched to Comp full rollers and have had no issues since.
