98 Dyna with original motor, 80in Evo. Bike already has S&S carb and a Thunderheader. I know there is not much to gain with the stock motor just looking for a bit more oomph.

Im guessing a cam is the next upgrade, but which one?

 

I put Andrew's EV27 in my evo fXR and the wife's Low Rider. Bolt in and I really liked how they ran.
