Good luck with that. I'll be curious how you achieve it. Perhaps you can burn a CD of an old shovelhead and play it full blast through your stereo.
To the OP, you're going to love the new cams. It may not be a 103 but you'll be fairly close when it comes to the seat-of-the-pants feel. Good thing you changed the barings. The stock barings are awful and can cause a lot of damage to your engine if they go bad. The guy who did your work is smart! Enjoy your ride.
