383 or 440 Dilema

I agree with Rob ---^ Flip a coin, or go with what your comfortable working on and knowing how to work on. the 383 is smaller its a B block the 440 is a RB block so will take up a little more space under the hood.....

Then you have to ask yourself, I use the 383, can I afford parts in the future? Again, you use the 440, will you be able to afford the parts in the future? Which is cheaper to maintain?

I always said, just because you can, doesn't always mean you should!

The 383 will do what the 440 does, but as said here, at a higher RPM, it would need to be pushed a little harder to reach the same numbers as the 440......
