ALL the 450 motors have the "E" in the serial... It designates engine serial as opposed to frame serial...... What you need to know is the "K" of the engine (and that's based on the first several digits after the "E"..........CB450E-3000002 for instance would be a K1 engine...

Pardon my ignorance. What I should have said is that I'm putting a K4 motor in a K7 frame. Like I said, I'm new but very interested. I'll post quite a bit before this project is over.
