95" cams
I did a build last year and went with SE perf heads with some porting, SE hi cop pistons and 257 cams I am right at 100/100 and I have had to tune the crap out of it. I went with a supper trap exhaust and I was able to achieve a decent tune but I am looking to go with different cams.
I'd like it to come on a little sooner and through the mid range while loosing the ping. I feel that the band is narrow and the bike feels to heavy for the cams because tuning is difficult out of the gate mid and top no problems. I was also going to open up the throttle body to 49mm by porting to get more air into her.
Any and all much appreciated!

RE: 95" cams
What is the compression ratio - as built?
Sounds like you might be a candidate for a Hippo Build, which uses the heads you have & S&S570 cams.
A HQ-575 should work pretty well too, depending on CR....
You DO NOT need a larger TB! It will only HURT you on the bottom. The 46mm you have is A-OK.

I was only considering the TB port because it sure acks like it wants more air... CR it has been a while but I think it was around 200 or 210

If you are at or around 10-1, the Woods TW-6 is a great cam for a bagger.............I'm assembling mine now and can't wait to try it out after this white hell stops falling.

OOOOPS 10.5-1

That is your Cold Cranking Compression, what we need to know is your static Compression ratio.

RE: 95" cams
If you want to compare cam specs, BigBoyz has a nice cam comparator feature on their website that allows you to compare three cams at once which is useful since cam timing is such an important element in evaluating how a cam will perform:

One reason you may not see the torque earlier is the257's intake valve timing; for example,the suggested cams have the same intake valve timing: 20/40, compared to the 24/48 of the 257.

I Have to agree with the others the cam is what you need to look into, don't change the intake it will do the oposite of what you are trying to acomplish it will drop the velocity of the air coming in. In turn droping your low end tq.

Once again look at the SE 204. Good duration on both intake and exhaust but it closes the intake valve early enough to give that great low end response. Also exhaust valve opens soon enough to let that baby cool off a bit.

RE: 95" cams
Awesome and thanks!
I think I am going to get a hold of a local guy that used to engineer for S&S, works at a shop near my home and see what he has for advice. He tuned my bike and we spoke briefly about the cam and as it was it was the end of the season so I really hadn't had time to get the feel of the whole tune.
I am going on the first ride of spring SNOW/or Shine 3/22 and will be doing some hard core iron but (the guys I take this annual run with ride Beamers and run very hard)! Then it is back for some minor surgery and 6 weeks down time. This should give me time to assess and reconfigure... If the results are not to my liking I will be completely doing a rebuild and then the real questions start!![/align]
