Oil Pump Shaft
I have an 86 vettte and Im reinstalling the distributor. Im using a large screwdriver to turn the oil pump shaft so I can get the rotor to fire off on number one. I noticed that i can wiggle the oil pump shaft around with the screwdriver. This is a new motor that hasnt been fired off yet. Is there supposed to be play with the 
oil pump shaft or did something come loose. I have a call into my machine shop but its the weekend. Its a high volume oil pump. I primed the engine and it oiled up good so i was wondering if this is normal play

Those suckers are as loose as a goose. You don't have a problem. If you look inside your distributor gear, you'll see how it gets stabilized on the top end, with the distributor in place.

Ditto, no worries! For just a few bucks, you can go for a hardened shaft w/ a steel coupler (instead of plastic) and I hope your builders installed this. If it's a stocker or mildly modified engine, you'll be fine either way.
