assembly oil

[tooze@vinny.cecer.army.mil (Marcus Tooze)]

What weight oil should i use on engine assembly...perhaps something
a bit heavier so that on initial start up things are still coated?
For that matter, what oil should I put in it for the winter, I
will be driving in the winter - something like 30w-10???
I'm in central Illinois (temps 0-40F in deepest winter)

By the way, its a '74 1275 normal stock engine (bored to 0.2 if
that makes a difference).
