I plan on eventually puting a 350 in my car and NA it will make around 290-320HP. I want to also make sure the shortblock can also handle a blower. I would put a slightly larger cam(around 214-224) and a centrifugal blower or use my NOS kit. Would the shortblock handle it? With the L98 it would give a 9.5compression, L31 would give a 9.6 and ZZ4 would be over 10, so I guess a blower wouldn't work on ZZ4 shortblock would it? I can lower the compression by a little using thicker head gaskets but I don't know by how much. The compressions listed is using a .038 gasket I think. Thanks

You can use a blower with 9.5 compression, but I wouldn't use too much boost (not more than 5 psi I think). There are plenty of supercharger kits for lt1s, which use 10 something compression, so I'm sure it can be done, but you just couldn't use too much boost. You'd probably be better off using lower-compression pistons made for supercharging/nitrous.
