everything is a trade off. must pay peter to pay paul.
i gave up some low end to gain top end but compensated by gearing ratio in the tranny.

Not necessarily. That CR 570 Scott mentioned will show gains across the board compared to the stock cams. 48 might also.

i have never seen where you change a system component and it did not effect it somewhere, including didn't work at all, that still is a change. everyone talks about cams but really, cams are NOT a magic bullet. i seen stockers smoke others where they thought the lumpy cam would was white on rice.
the same for headers. some think there are massive power gains which sometimes is a power loss, just throwing parts ain't the ticket. he wants sound but does not care about power, then install a stereo system, they do it in muscle cars nowdays.
all i said was i willing to take a loss on low end to GAIN top end where i want it. to compensate, i geared down the tranny 1>4 and went international final ratio. it still performs as stock + some since i have torque multiplication. i also shifted the power band 500 rpm up scale and it really doesn't start coming on till after 4k.

You're missing the point and more or less comparing apples to oranges (your bike's state versus OP's desired condition for his bike). OP likes torque--570 delivers that in spades. OP likes lumpy idle--the 570 will have a slightly lumpier idle than stock. He'll gain power throughout the range. Win. The tradeoff? Quite likely a cooler running bike, the same or even slightly improved mileage, PLUS (compared to your bike) stock gearing which retains good manners on the freeway AND the ability to accelerate well without shifting down 2 or 3 times to get the revs up to 4K. Can't see a downside here....

With that said, I'm not here to argue. The OP clearly has a vision for his bike that is different from the way yours is set up. And I believe he can get pretty much what he's looking for, plus some, with a simple cam change and a tune.

Peace out.

I'm not trying to get people to argue. I was just looking for opinions. Like i said before was looking for a cam that was general good in stock 103. Sound only is what i'm looking for. I ride with a couple of guys who have dumped cams in there bike yeah they get me off the line drag race style but rolling iv out ran them. i am very pleased with what my bike does for being "stage one". just love that lobe sound of a cam. Sounds like martin gets what i'm saying.

the whole point is: RESEARCH
do not care what others do since i do not ride their machines. why throw money at something that might not transpire?
i posted MY experience as an example, i know fully well what he wants but getting there is what he needs to focus on. everything else is speculation.
how many times did you here someone say "i put headers on my engine and now i have 20% more power"?
i ask, "did you tune them"?
nope they say, says tuned right out the box!(some truth but not whole story)
reality check! probably has a power loss since he never used the collector extension and dyno, sure you can run open headers but adding and exhaust makes a big diff.
everyone likes diff things, he likes sound, ok, i like top end, sound not important. i run 120 @ 5k and just getting started, not everyone's cup of tea for sure.
truth is i hope he finds what he wants. stereo system is cheaper, never thought that they would play muscle car sounds through the speakers to let the driver think he's got a roller when he's actually got a walker.

One over looked cam is the Woods Tw-5-6. You can call Scott@hillside or even Rosa's in Huntington NY. Both builders are very good at what they do.... Not knocking the 48 or the 570 can't go wrong..

I don't pay any attention to posts like those that bustert or others put up that don't at least make an attempt to answer the OP.

If I was the OP, I would leave well enough alone, 100TQ at about 2300rpms peaking at 3350; what's not to like. Leave it alone until funds are available for head work then do both, heads and cam.
