Yet another cam question.
So I'm starting to plan a small build. I have a 07 dyna, 96", Sampson Streetsweepers (true duals) when I bought the bike it had the SE intake. I never had it tuned after I changed exhaust cause everyone said I wasn't necessary. But the time has come to coax a little more from the engine. I have so many cam threads and even the main cam sticky, the numbers are just starting to string together.
What I don't want: I don't want to bore it out, I don't want a cam that I will want to change after 6 months (I know people will say go with Andrews 48, but to many people end up changing them out of something a little more).
It seems to me from the reading, goals can be met with the right cam, a CR bump, and some head work, maybe some other changes..
I usually stay in the 3200 to 5200 RPM range. I like to get to my cruising speed quickly, and then mildly cruise. I often shift to 6th around 85MPH. Just want to keep up a bit more with my bros.
Thoughts?

You're willing to do heads, cam and tune, but not bore and pistons? You're right, you can make big improvement, but you could make a LOT BIGGER improvement for a relatively little bit more $.
What's driving your decision, budget? If so, I think the 48 might be your answer, in spite of what you said about it.

You're right, a big bore isn't that much more. The reason I said don't wanna bore is I honestly don't see why big bore.....I could get good gainz without bore, I know not nearly as much, but gainz none the less. Bigger isn't as reliable, right?
I mean, does one really need the bore?

Boring to 107" is the cheapest TQ/HP you will buy and yes, bigger is just as reliable as stock. Start with more displacement, select a cam and have the heads worked to fit the cams. Or install the 48 and drop a tooth on the trans pulley.

After reading the advice given then your responses, it seems your mind is set. If you think 107 is no biggie from a 96 and domed forged pistons are no biggie over stock flat tops and that most people if choosing bore or heads only choose bore and if you want to be limited to a lower compression range with less and smaller cam choices, the go ahead...have at it. It's your bike.
