On a second week of November built L78 for a Camaro which water pump would be correct.

I would imagine your talking about a 1969 Camaro?
If November of 68,agree on the #065.
If November of 69,don't exclude the #811 entirely.

It is a 1970 L78 Camaro with a November 1969 Tonawanda built engine. When did they change to the 811 Water Pump?

I have seen some veeeeeeery early 1970 production vehicles with the #065,(Aug.~early Sept.1970 assembled),as they probably used the old remaining inventory up first at various plants throughout the country..and there was overlap w/the #811,so either one was possible.
I think they started casting the #811 pump in mid 1969.
Honestly,I would opt for an #811 on yours.

Sorry Mark,

If you're talking about November of 1969, than the '811
is the one you want. Interesting that some early build
1970 cars used '065 units. I would have thought that they
were long out of invertory. Oh well, they were probably
being used as door stops, paper weights, and to hold open
windows... http://www.yenko.net/ubbthreads/images/graemlins/rolleyes.gif
