Welcome to FBBO from New Zealand.
had a 56 chevy belair with lift off hood cool stuff but what a pain cant do without a partnerIf you want the power of a 440 Sixpack, or a stroked 440 with a Sixpack on it,no harm in swapping out the 383. If it is original to the car,than keep it in a safe dry place in case you ever want to swap it back or sell the car. A 440 Sixpack with a lift off hood is a nice upgrade! Welcome to the site.
