Hey guys I'm new to building cars and i have some questions I have a 1995 ZR28 Camaro it has blown headgaskets and has been sitting for over 6 years i want to rebuild it with a procharger or some sort of supercharger so what I'm asking is what parts should I use so the LT1 can handle the stress of a supercharger. I also want to make a minimum of 400hp

 

You can make 400 hp without a supercharger easy enough and your stock lower end rebuilt is plenty strong enough for that.
Get the heads ported by someone that knows what they're doing, get with a good tuner and have them spec a cam for you and associated parts like lifters cam chain valve springs and pushrods,get a good set of long tube headers and no cat y-pipe with a high flow exhaust behind it then have it tuned.
That should get you close to 400 hp at the wheels on a dyno and still be reliable without the expensive of a supercharger.
