Opinions wanted: 408/416 Stroker or 440?

too much stroke and too much hp for a stock thin wall 340 block casting. go with a 400 big block, headers, aluminum intake and heads. much more reliable and sustainable horsepower. 340 stock heads and you need hardened valve seats and even with aluminum heads it wont flow as much air as a good set of comparable big block heads. big block. easier to achieve high horsepower with out aftermarket bullet proof parts. and you can add to the big block as you go with aftermarket bullet proof parts like stroking, aluminum heads and wild streetable camshaft grinds.
