I'm planning a build for next winter. I've got all the details worked out except the cam choice. I'm working with a 07 duece 96inch motor all stock except a stage 2 breather vh big radius 2 into 2 and a cheap vh fuel pac ...can't complain it came that way. I love the look of the pipes but I know they are not ideal for good power. I'm planning on boreing out to 103 upping compression with some good pistons and thin gasket got a local guy that's supposed to be good with head work and tuning so that's lined out just , just can't come to a good conclusion on the cam choice. I want a hot rod with a very punchy hit on power and a big nasty idle I ride 2 up very little and mostly back roads so Im wanting good power but not so much that I've gotta start bullett proofing everything else. I know there are a lot of cam choices out there, so many I about don't know where to start I've read hundreds of threads on cams but most are dealing with touring bikes not softails. I'm doing all the work myself except the head work and tuning so any and all advise or experience is appreciated
Everyone has their favorite cam set. You should be looking at dyno charts for 103" builds and find a chart that shows the power delivery you want; there will be several different choices that will all deliver similar results. However, don't get the cart before the horse; do the homework, select the cam first and build around the cam.
The most overlooked performance options on a softail(or any big twin) is to lower the gearing. It's not cheap but, but is something you feel and doesn't affect reliability. You can go a little less radical on cam/ compression and keep long term reliability. Evo- industries makes a 49 tooth clutch basket or you can go with a 30 tooth front pulley. The pulley requires a new belt and a bit of labor. As far as cam, andrews 48 with headwork at about 9.8-1 is killer. Good luck!
talk with the guy who supposed to do your head and tune
he is suppose to know what work good with his work
what kind of result he got with different cam
Ding Ding Ding The pipe/intake/head/piston combo need to set to the cam and riding style. THe guy doing the heads and tuning is the guy ya need to talking to. If he can't/won't help ya; Stay away!
So many guys on here know their stuff and Im not one of them... That said Ive done enough research to know the 204s make a good sound. If you plan on doing head work though likely you want more cam, maybe 57 or 54 or 570, 585... so thats what I like anyways. I know tman and woods cam are real popular as well, but my personal preference is Andrews or S&S. Kinda a long story as to why & the fun part has been finding it out! Good luck with your build....
oh yes so after going back and forth between the 204 & 57 I finally convinced myself to drop the SE204 cam and SEST. I have the andrews 57s sitting on my desk now and getting ready to install this winter. 103, no headwork, TTS, Stage 1, lifters, pushrods, bearings and SE clutch spring. Although a mild street port on the heads w/ a .030 hg keeps nagging at me. will see.

You won't realize the potential of that 57 until headwork is done.

I wouldn't fool with boring and pistons.
Good 82cc Headwork, .030 HG, good exhaust, good A/C, 26h will put a smile on your face
