heres a compression ratio calculator... not sure if you already knew about this one. it seems pretty easy if you measure your stuff, gakets, ect

i get about 9.5:1 with the stock 3.875 283 bore, and a 3" stroke... assuming the piston has no dome at all, and assuming theres a little bit of deck clearance (maybe .010-.015"?), and a 60cc combustion chamber, and .025" thick head gasket (pretty thin, i think most sbc head gaskets are more like .045")
