Inliners International Forums General Discussion Engines BB Rocker Arms

The power manual says big block rockers "can be used as well as rockers made specifically for the Chevy six". Do we give up anything by using the BB rockers on the late model Chevy six? The choices, availability and, in most case, price is much better with the BB rockers. It looks like we may have to give up approximately .01" of lift because of the differences in the ratios but as long as we know that when selecting the cam, it shouldn't be a problem. Is there someone using the BB rockers that would let us know if there are any problems ?

I have been running the BB 1.7 rockers for the past 19 yrs with out any problems I have now switched to a 1.73 rocker with this new motor I'm building. I just figured after 19yrs It was time to buy some new ones. (Which Still are BB rockers) (comp cams rollers) Hope this helps. }[oooooo]

Will big block Chevy guide plates also work? The power manual shows a picture of a package of Olds guide plates but doesn't really address the issue in the text. Are guide plates needed with the roller tip stamped steel rockers and the regular roller rocker?

If you are useing the stock size push rods with a low to mid. lift cam Then I'm not sure that i would worry about the guide plates. But If your useing bigger push rods and Cutting the head open for the bigger size rods and a larger size cam, Then Yes I would think about useing the guide plates. I have run the Stock size push rods with a 600 lift cam and have not had any problems in 19 yrs of running this motor with out them. But everyone has there own opion on what they Like to build there motors. Hope this helps.
