I thought I did but found out that my distributor was not seated down far enought into the block to properly engage the slot in the oil pump. I found out by measuring the screwdriver shank that I was using to spin the oil pump. I measured this against the distributor shaft marked at the point it was mounted. I was about 1/4 inch short. I loosened the bracket around the shaft and kept fiddleing with it and it finally dropped on down into place. No more oil pressure problems.
