Rocker shaft replacement????????
Chrysler's Rocker Shaft rocker arm arrangement is the best , bar none .
Easy to work on , and hard to screw-up .
They were fully-pressurised-oil-fed , and they would retain a spank of oil in order to avert dry starts .
The so-called "Banana Groove" was an oiling trough .
From what I remember from the Mopar Action article (read it at lunch yesterday at work) , only the 1970 Trans-Am 340 and '70/'71 Hemi had different-material rocker arms (i.e. , not stamped steel).
The *only* thing to watch for (other than the usual application of break-in lube on the pushrods' tips , valve stems' heads , pushrods' seats on rockers shafts , and the rocker shafts themselves ) when installing new shafts , is to make certain that the oiling holes point the correct direction (!) , and that the retainers are properly torqued and in sequence :cheers: .
