Someone mentioned an andrews 48,good choice.The biggest problem with the bikes is the gearing. It's a lot of work,but even a change to just a 31 tooth pulley is well worth it. If you don't ride over 80,go with a 30 tooth and a new belt. Of course it would be nice to have the lower gearing of DD-7and still have the lng top gear.................................

Likewise, mine is finally done. 100tq and 91hp. Your heads are getting you a bit more, but I'm totally stock on the top-end.

I've said it more than once, it's hard to beat those 204's, if I ever go with a 103" engine I wouldn't look for any other cam, why try the rest when you've got the best, 204's.
same stock cam as in the stock 96 motor.

There's not a lot of internal differences between the stock 96 motor and the stock 103 motor that's going in most of Harley's big twins now. Bigger jugs and pistons, and a couple of other minor things, but the cams remain the same stock smog cams.

I just had my 09 Ultra moved up to the Big Bore 103 Stage II with the 255s and sert with Rhineharts. All my torque is down low and pulls like a freight train. Its exactly what I wanted and I really cant see much difference in either one. You will get a lot of advice on here and most of its very good. I think the main thing is to get a good tuner.
