The 440 means a different intake and distributor due to the raised deck height.
Thank you and that's why i want to stick to a 383, plus i just like the engine!
Intake and distributor are not even and issue in the big picture, especially if you are buying a complete engine that has been run .. it'll already have those parts on it .
You have the oval air grabber air cleaner , I think??? , that's your bigger concern because it'll hit the hood with a 440 if it's a 383 unit and/or the 440 has an aftermarket intake.
