I would pull the valve cover and oil pan and pour break in lube (sometimes called assembly lube) on the lifters, rockers, cam, crank bearings, and piston walls. You can get break in lube and oil at Carquest and such, it should contain HIGH levels of zinc or ZDDP. If you can not get break in specific oil get any conventional or semi conventional blend, and add ZDDP yourself. Modern synthetics have been rumored to wear old style flat tappet cams excessivly due to lacking lubricity. The zinc is a high pressure lubricant that used to be in the oils when this car would have been new. I ran my break in oil for about 100 miles then changed it out.

When you do fire it let it run for ten to fifteen minutes altering the RPMs between 2000 and 3000 in steady movements (don't just blip the throttle but cycle it in that range). This is to ensure that oil is splashed and pushed around the entire rotating assembly. (This was the break in that Comp recommend when I broke in my new cam.
