383 cui Stroker

Hello everybody, I have a question about 383cui Stroker. I always thought, such an engine is a 350 with the crankshaft from the 400s. But finally I read about “destroken”. This should be a 400cui block with the crankshaft from the 350s and also this should be a 383?! Can this really be?! And what more to recommend/better? Greetings Camaro
