348 was a very good engine for its time,the original Chevy big block.A lot of streetrodders using them today for installs in 58 thru 61 Chevies.Very pricey to set up.You can get an awful lot of horses out of a 350 or 400 small block for a lot less money.Or stroke a 350 out to 383.Not that there is anything wrong with a 348,but its gonna cost a small fortune.
