I'd say if you're wanting to stay 302 based, go with a 331. Always go with a mild stroker if it's going to be a street car. Over 10 yrs ago my coupe with a bone stock shortblock, TFS High ports, carb and a C-4 I went 11.74@117 with a nitrous cam. That run was NA with WAY to big of exhaust.
However, if you want a good base then like mentioned, go with a mild 351 stroker.
