I have a 2003 FLHTCI that went through the S&S long block program. It's now a 106" with gear drive cams. I also have a 2006 FXD that has a bone stock motor in it.
I no longer ride the 2003, I ride the Dyna everyday in the summer. My question is is it possible to swap the 2 engines? If it's not doable, I'll likely just end up upgrading the 2006, at some point.
I did a quick check and it looks like the inner primary housing is different, but I am not familiar enough with with all the differences to to say weather or not it's possible, hopefully somebody with more knowledge will reply
The 2 motors are not interchangeable. 06 FXD is a six speed tranny and 03 flhtci is 5 speed. Primary and oiling system changed between the 5 speeds and 6s. The 06 dyna needs and 07-up bagger or dyna motor. (or 06 dyna)
I'll be damned, I retract my previous statement. I made an assumption they all had the same bolting patterns and oil pump hookups onto the transmission.
