Claims the Cam and Distributor will wear out prematurally if it isn't reinstalled? I asked the guys at the machine shop if they replaced it or used the old one. They said they replaced it but didn't put the hole in it as it is no longer required (according to some software they have). Can anyone tell me IF they are correct or do I need to have the hole drilled in? Thanks.

This is the same machine shop that didn't know about the 45 vs. 39 deg bank angle????
Considering that Olds stopped building big blocks before the PC was even invented, I'm curious about this "software". That 0.040" hole is what lubricates the distributor drive gear. I think it's time to find a new shop.
By the way, is this shop building your heads for you? Do they have the Olds-unique gauge to set the valve stem height after grinding the valves? Do they even know about it?
