Re: [FWDLK] RB 383 cam



Thanks for the input guys.  I agree about the oil.  I've driven the car a total of about 10 miles since buying it from another list member who also didn't drive it during his ownership I believe.  There is a receipt from a commercial garage showing a ring and bearing job, but the receipt has no date on it.  The inside of the engine is very clean and the oil isn't bad either so since that minor overhaul it must have been reasonably maintained, but of course with low ZDDP oil like we are all stuck with in the mainstream oils.  I'm thinking of using rotella once I'm back up and running since I don't have a converter to get clogged up with zinc.

Oh, that must be absolutely true, because nobody in the old car
hobby knows about the effects of NOT having ZDDP in flat tappet
car engines.

And, of course, the ruined cam shafts render the car and its engine completely
unrepairable and worthless.

The car mechanics, in particular, hate the effects of having to work on these
damaged engines.

Bill,

You might give some thought as to WHY the cam has developed 3 bad lobes.
Here is a good article about how "OIL IS KILLING OUR CARS!!!!!".

Personnally, I think this is a plot by the EPA to get old cars off the roads quicker, by removing the ZDDP from our oils.

 Hello all, I tore into the '60 Saratoga engine today, an RB 383, and as I suspected from the symptoms, it has a wiped camshaft.  One lobe is just a little nubbin', and two others are clearly half what they should be.  Seems like a simple cam swap is in order except of course for the small matter of early B/RB lifters and pushrods being different dimensions from the later ('66 and later?) stuff.  From a previous experience with putting a cam and lifter kit into a '65 engine, I think I recall that the late lifters are taller, and must use the late pushrods to compensate.  I could have it backwards, but in any case, I think the solution to using a late cam and lifter kit is using the late pushrods too.  I have several core 440 engines and I'm thinking, make a cam selection, buy the late style lifters with it, and use a set of the 440 pushrods (being that both my '60 383 and the 440's are RB engines with the same deck height).  Comments/cautions/suggestions?  This is not my hot rod and I plan to go with a pretty mild cam.
