Hi, Bob,

I was in Cal State Hayward when it was a bare hilltop, back in 1972.

In the Bay Area, 20w-50 would work. Some of my sources say, since no post-cat cars ever specified 20w-50, it has not been reformulated to remove as of the wear additives as the 0w-30. However, as per Jeff Rice and others, there are enough other additives and the spring pressures are low enough on your 327", you shouldn't have problems with 10w-40.

thnx, jack vines
