Oh! Now that's a different ballpark, but I have done it several times and several ways. First you will need a big block transmission, then you can either use Schumacher small block to big block motor mounts or solid body mount's that bolt between the water pump and block. You can use your same transmission mount. Then there's the exhaust, headers for big block A body will be easiest to find, you will need a bigger radiator, and if you use tall performance valve covers your heater blower motor will be in the way. This will be alot more complicated than switching to a 340, but it's not that bad.
