So what is the zinc and phosphorus level of the high mileage oil ?
And how much does the ZDDP raise it ?

OTS - Welcome to the Corvette Forum. Do post up some pics of your 65 L78 when you get the chance.
And, if you have never visited the C2Registry.org website, check it out. On the 1965 listings, due to this being voluntary, nothing official, they are up around 6% listed of the total made in 65.
And I and another Forum and NCRS member, Gary Cowans, have been compiling a list of all the 65 396 Corvettes we come across and so far, are up to 396 (appropriate number, right)
out of the original 2157 made in 1965.
To see the L78s in that list, just hit Control-F and in the search box in the upper right hand corner, enter 425 and all theL78s will be highlighted.
