Will the rocker arm assembly from a 1954 power glide engine work on a 1958 261? The assembly on my 54 engine only has about 4000 miles on it and I would like to use it if possible.

Thanks, Pete

I think you should be ok, but read this article— it's super helpful!

Early rocker arms on a later motor can lead to crazy oil pressure at the rocker assembly. I experienced that and had oil squirting everywhere when the engine was running and the rocker cover off. It's due to the oiling groove being offset on later rocker arms. Anyway, that article helped me get things back under control!

I know there is a difference between the early and late years, but I don't know what the difference is. Ram_51 or Gene Schneider would know.

Personally, I'd match up the part numbers in the Master Parts Catalog as a beginning point. Not to say they wouldn't work...but a different part number would indicate some sort of difference. A difference that may translate into improper or poor performance.

It is possible that the shape of some of the rockers may differ depending on the cam and hydraulic or mechanical lifters.

I had the drilled head bolt in my 62 261. Oil up from lifter galley. Don't recall how oil was transferred to rocker shaft up top on head.
