    Size!!!  LOL!  350 valve covers are rectangular, big block valve covers are more contoured -- second obvious difference.  You got a 454, there's not a whole lot of room in that engine bay, 350 you can see the driveway underneath the car looking top down.  :) And the sound!!  OUCH!! 

    By looking at them!! Now, follow carefully, which one of these engine blocks looks bigger? Which one looks smaller? Voila!

    Look at the valve covers, 350 rectangular, 454 contoured-- Rounded. All GM big blocks have that cover.
