The most obvious diff is 350 CUBIC inches is much small that 496 cubic inches. Also likely the 350 is a small block where as the 496 is a big block. The 496 will be a physically appearing bigger motor if that is the case. With great displacement also comes greater power or power potential. A mildly modified 350 can produce more power than a stock 496. Big Block Chev weighs in at around 675 Pounds and a 350 small block weighs in at about 575 pounds.
