I’m about to run 70’ of 3/4 piping for my shop air and I have a quick question, I’ll be running a DA, Paint, and Blast cabinet, not all at once but those are my high demand tools. The compressor is a Quincy-2V41C60VC and it has a ½” outlet, does anyone know if that outlet will restrict me in any way? I’m going to run ¾ piping either way but I’d like to know if that outlet will be a problem or not, if so if there is anything I can do about it.

"it has a ½” outlet, does anyone know if that outlet will restrict me in any way?"
Any reduction in pipe size causes restriction. Manufacturers have undersized small ports for the checkvalve and delivery ports to save a buck. Remove one of large side ports plugs of the tank, get a reducer down to 3/4".

The real problem is that compressor is too small.
You will store fractionally more air in the 3/4” lines but the 1/2” output is a relative constriction. Is your output ball valve female on the output end? If so you will have to insert a 1/2” male to 3/4” reducer and this will further constrict the flow, so maybe you really will not need 3/4” lines. Just a thought.
I'm not too worried about the size of the compressor, it runs my DA great but at the moment it is running through a 75' 3/8 hose reel that is reducing my cfm. I usually run the DA constantly for about a half hour and the pressure won't drop below 150 psi. I guess I really won't know what it will do until I have the lines installed though. I think I will have to solve it by doing what pcmeiners said and replace the bung that the outlet is on with one that has a 3/4 connection. The bung itself looks to be about 1 1/2" maybe, I think the first thing I'll try is taking off the original bung drilling, and tapping it. The bung current has a 1/2 female hole with a 1/2 male ball valve attached to it.
