Yeah, I've been really impressed with the details Aaron responds with in his emails and am starting to lean towards just going with Hammer. However, I owe it to myself, and my wallet, to perform my due diligence..... I only want to do this once.

 

Agreed. That's why I left that for the final decision before I squeeze the trigger on the build. I have been doing a bunch of research and have spoken\emailed with several head porters. Right now I have it narrowed down to one of the following:

I'm reposting my previous reply to your post because I figured out how to "quote" the message I'm responding to..... F#$#%^&N forum newbies!!!!!

BigBoyz (http://www.bigboyzheadporting.com)
Hammer Performance (http://www.hammerperf.com/tcporting.shtml)
NRHS V-Twin Performance (http://nrhsperformance.com/cncporting.shtml)
or possibly S&S Cycle (https://www.sscycle.com/go-fast-show...ystem-upgrades).

I've looked around at a few local shops, but I'm still leaning with the porters above.

 

So, my Dyna is probably on the heavier side for a Dyna because the accessories add weight; hard bags and cargo, fairing with stereo, floor boards and highway bar (see pic in one of my previous posts in this thread). I would prefer the cam to kick in at a lower RPM than the 3100-3200 you mentioned. Im wondering if the additional 3CCs (95" to 98") will make any difference? Also, I heard of folks add some type of cam offset to shift the timing.... not sure though.

 

Thats great to hear.... I love those numbers. What RPM range does the cam kick in at? Im not a phsyco rider, but I do like to jump on it once in a while, so the useable RPM range for the way I usually ride would be roughly 1800-4500, give or take. Just wondering if I selected the wrong cam to get that range.

 

I would have to agree on the 45.....

 

For that RPM range you might want a different cam - I run a similar build - 95" +.020 10.6 static/ 9.9 corrected/ 207 ccp - head work/ 1.9 intake - gear drive - Thunderheader - with a Woods 6H .590 lift + 4 deg It hits at 2800 -2900 until 5K plus. I don't know the numbers - it's never been on a dyno. Eastcoast Jim

 

I suspect my small carb could be costing 10HP at higher rpm's, but going too big is a problem at the bottom end, can cause sluggish throttle response. Took this bike on a 200 mile ride today, enjoyed every minute of it.

 

The S&S 570 would have been better all around cam and if you’re never reving over 4500 may look at the s&s 551

 

So, I checked out the descriptions on the S&S web page and here is what they had to say, and my comments:

551 - This is a bolt-in cam set designed for stock or mildly modified touring bikes. I don't have a touring bike, so I'm not sure how much of a difference that would make.
570 - This cam will provide a nice power increase across the entire power band. 3200-5700 rpm. The cam doesnt kick in until 3200 RPMs.

Going to do some on some Andrews and Woods cams now. Thanks.

 

The 570 cam is a lower rpm cam the the 585 you have in the list and 551 works in the rpm range you mentioned. It’s a early tq cam and comes on very quick. Andrews and woods have nice grinds. For my riding style I like the Andrews 37. Which it also kicks in earlier than the 585. The 585 is really a hot rod cam for people who like to run it through the upper rpms

But if you already have the 585 then Aaron can give you the best advice. While your looking around check out wfo Larry as well he does good work.
