brakes

I heard applying the brakes can affect the steering feel with hydraboost, is that true at all?

No, not true IF your system is set up properly with the correct sized components. I have been driving hydro-boosted Astro's for 12 years with no noticable steering affects when applying the brakes.
If you go junkyard shopping look for anything before '97. GM changed the angle of the booster on the firewall and (I think) '97 was the 1st year for them. These boosters point down, toward the front, at about a 15 or 20 deg angle. The previous years came straight out of the firewall. I am using a '95 unit on Bad Ast and it bolts right up.

I guess with a first gen Camaro install there isn't such easy bolt up? Do you know if my 1" bore (Corvette) manual master cylinder can be used?

Not sure about either. Someone that has done the swap will chime in. Maybe make a new post to ask that question. I do know most of these bolt patterns have been the same for years so maybe you'll get lucky.
If you want to add a vacuum reserve canister to your current set up that may be all you need. I ran a very lumpy cam in my '73 Firebird for years with just a vacuum canister hooked up. Worked like a charm.
