Scott, i'd like your input. I'm considering changing cams only this next year on my '16 Wide Glide with a 103HO, and V&H 2into2 Big Radius pipes. The 2 different cams i'm looking at are S&S 583, and the 585. I'm not wanting to loose any bottom end over the stock cams, and would the S&S 585 keep my bottom end and give me a little more up top? It's a bone stock 103 except for the pipes and a tune. Thanks for your input.

 

Those two cams are very different. The 585 cam will be very soft down low with stock comp.

 

Plus you won't get much out the back door with any hp cam using stock heads.
If staying w S&S the best bet is the mr103 in stock application.

 

Of those 2 cams, the .583 will suite your needs better, but Dave makes a good point as well.

common mistake we get all the time from riders.the 583`s & 585`s are two completely different cams.while the 583`s are very nice for low & midrange at moderate compression (we set them @ 9.8-1),the 585`s are more of a hotrod,high RPM cam with compression set at a minimum of 10.5-1.

 

Thank you to ALL of you guys that replied!! I really appreciate all the info I received, and when I went back and reviewed the info on the 585's, well let's just say I may have had 1 to many when I read S&S's info. Like Dave said the MR103 looks a lot more like what i'm after. Is there another brand of cams and specific part # any of you guys would suggest over the S&S 583 or MR103 on a bone stock 103 other than pipes? If not, would the 583 or MR103 be the best? Thank you guys again for your input.

 

Andrews 57 or SE 204
The SE 204 will give ya that badass, nasty idle

 

Excuse me if I have a chuckle at that! My S&S V107T Evo came stock with a 585 and CR of 9.5:1. Pulls like a freight train with a wide flat torque curve and is a great ride. I'm sure you chaps could wake it up a lot more, but with the Atlantic in the way it will have to stay as it is.

 

chuckle all ya want pal.585 cams set at 9.5-1 will be flat as hell,REALLY flat on the bottom and with compression that low,wont make any real power in higher RPM`s either. try bumping the compression up to 10.5-1.im sure S&S has the compression that low for EPA regs

 

Well it ain't that flat, which is the point I'm making! And it isn't an EPA engine.
