keep or sell original single barrel intake

I have recently done a super six conversion on my '70 duster. It works great I might add!
I have no intention of going back to the original intake system. The "super" is exactly that! So, I got the car from the original owner couple of years ago...69,000 miles! It's original except for some upgrades I've done...power disc brakes, nice slot wheels, stereo (no dash cutting involved)...just the stuff to make it an easy driver. Should I sell all the original intake stuff or keep it with the car? Your thoughts?
