Folks -

A newbie here, signed in under the wife's moniker...

We are thisclose to buying a 47 5 window 3100. I've been poking around for several days on various links (the "we love chevrolets" blog is the BOMB).

If I understand correctly, 47-53 216s all had dipper lubrication, no pressure, no oil pump... Is this correct? If so, how the heck did they get oil up to the rocker assembly and valves?

I have also seen a couple of references to "partial pressure" lubrication. Can any of you folks fill me in?

If I ever had to replace the 216 with a 235, what would be the best 235 to swap? Is there a particular year or serial number range?

Thanks in advance,

John Moorhead
