Obviously personal experience is different. I know I won't get a tire-scorcher in there with a stock CR and stock headwork, so my options are limited. But like you and many others have said, the 48 looks good. Thank you. I think I'll grab a couple of those.
If you were looking for a strong low end, the S&S 583 would also be a good choice but I don't know how it performs on the high end; haven't seen any charts; it might not deliver what you want on the high end.

It seems the only way to get belt-snapping low-end with high rpm horsepower is to get a Procharger...hmmm... Lol.

Gonna need alot more than just a set of bolt in cams for what it seems you're wanting. Get the check book out.... you're gonna need quality heads, a 103 SE or 106 with S&S big bore, bigger cams and a good tune.... Bolt in cams for your application won't produce the power it sounds like you want, AT ALL

I've got tw6-6 cams in my bike. The heads were shaved for compression and 106 ci.
Bike makes 107hp/115tq. Hits 100tq at 2200/2300rpm(I forget) and the hp doesn't drop off until I hit the rev limit.
Apparently they are similar to woods 555s. As far as power these things really move my dyna.

Djl: I've done chains on other bikes, never a belt on a Harley, however.

Matt816: I know this full and well, buddy. The check book will only let me do cams and intake currently. I'm no stranger to building motors, but I have no shame in admitting I need schooling on my Harley. I'm not expecting a pro streeter from mild street cams.

Shredding rubber: I'd love to hit the 100/100 mark! And then surpass it.

Bigdog1949: I hear compression releases are a must-have if you bump up the CR. HD has a tool to install your own. Doesn't look too difficult.

Taken from the other site.... Probably could tune a bit more in there with a good pipe and better tune.... Andrews 48 cams, stage one with true duels.. otherwise stock 96 inch 2010 bike

A bolt in cam set to a Stage I 96"er is a good place to start; then the check book will come out if cams don't get the OP what he wants. For sure, he won't get "belt snapping low end and high end horsepower" from a set of bolt in cams.

Bob Street, you don't want to change the belt on a Harley.

Matt: Thanks, that pull provides a good basis to look at. However I'm planning on a good 2-1 exhaust because of its scavenging properties.

Djl: Haha I'm sure I don't. It was more of a figure of speech than anything. From what I gather, however, these drivetrains can handle significant power increases with minimal modifications.
