Pratt and Whitney Canada Boeing 720

If it's a -420 which I started with you have to change the trailing edge shape and the flap lines as well. Plus you need a different engine config as most 720s only had one, or two at most, turbo-compressors.

Is that what the small air intake is for on one of the pylons then Kit

Yes, that's the thing.

Depending on the individual aircraft there can be any number of them from zero to four! The BA freighters had three of them, as did many PanAm -320s but it's a minefield for RW modellers. Of course here in WhiffWorld we can install as many or as few as we like.

Got on board that P&W 720 once when it came into YYZ, also happened to be one of the rare days I didn't have my camera with me.    Somewhere in my mounds of crap I still have some publicity handouts they gave us.
