B764

Haha I never know how to tell the difference between the 300 and 400

The 764 has a raked wingtip. You can't see it in this picture.

Also a Boeing 767-300 has turbofan engines and the -400 has turbojet engines if you check the registration

FSXBoeing737Pilot, you are wrong. Both the -300 and -400 have the same engines, Pratt & Whitney PW4000 or General Electric CF6 engines. The only major user of Turbojet's are the MD-80 family.

B767-400

You can usually tell the difference by the windows and their positioning aft of the 2 L&R doors. Many 763's do not have 2 L&R though some do.

A B764 is longer than a 300
