There is room at the top for many
The 37 and the 204s very old grinds still work awesome.
A higher lift trend is in motion and these oldies only have .500 or so lift so they get overlooked. They will run right with the best of them especially when the heads are stock.

the  211 is another cam that works well, but again the lift is not any differant than the 204. but will get more hp and tq.  have noticed that a cam such as the 211 gives bout the same ##'s as the 259 all things being equal. the lift is a lot more on the 259 but its a epa cam.  the 251 is old school i suppose?
like you said lots of greast grinds out there.  i still like the  old HQ 33. ran it in the 93 evo and it was a tq cam plus it pulled hard all the way to red line.  justs took a loto compression . gas was better tehn too.

The 204's are the ticket, they worked well in 88's 96's & will shine nicely in a 103 very similar bottom end performance with room to carry the line some to the right, they'll breath a tad better then the 255's at higher RPMs.

What amazes me are the many negative postings I read on the net pertaining to the 204 cams. Huge amounts of chit posted about the 204 and how they are only for light bikes and on and on.  Dam shame 

the little 204 seems to suprise a lot of people.

The 211 may have seen better days.
Low lift combined with generous overlap has left that cam behind in this predominately EFI market.

you are prolly right. seen a couple dyno's recently where they get into the low 100's hp with a 103. the HC pistons, a/c,exhaust, and a little clean up of the heads is all  decent tune.

your plan is great! looking for some great deals too.

wow thanks for posting that video, good stuff

On cam choice, if the the 255 is such a great cam then why is everyone pilling them out?  Max

Because they think they want less torque where they ride and more horsepower where they don't?  Who can say?  Probably Internet forum members following trends like lemmings.  Actually, who can say how many are really getting pulled as opposed to installed or just retained?

I'm glad at least one person I know pulled a set.  That way I could get them for $75, have the dealer install them in my new bike, have better performance over stock in exactly the places I run the engine on a day-to-day basis, and retain factory warranty on the engine internals.  Maybe in another year and a half I'll consider some other options.  Maybe.

OK I got it.. Buy them cuz they are better than stock then dump them later a better cam...  Max

The 211 compared to the 204 are 2 diff. animals.  The 211 comes on quite late due to the longer duration and the later intake close will cost you down low.  No comparison to the 204.  You gotta be above 3K'ish to feel the 211 come to life.

Anyone with a link to dyno results for the CR 575? or can post a sheet?

You have a dealer that would install used, customer provided parts, AND honor the warranty on the engine? C'mon, really? What dealership is this?

I had him (the owner) specifically check first.  He called the mother ship and they said those cams were street-legal in a 103 so warranty would remain intact.  I don't know whether he'd mentioned the cams weren't new in the box, but afterward he told me it wouldn't matter where they came from; so long as they were the specific part.

Yeah, I know.  Almost unbelievable, but so was the price he sold me (a first-time customer) the bike for.  He's been selling Harley for many years, so I'm going to trust he knows what he's doing and how things work.

I reckon that since he was the one that pulled the cams in the first place and knew their history might've been a factor...

I have the 96 with only the SE 255 cams and they make the bike more rider friendly for lack of a choice of words.
The gearing for your 07 is going to affect your passing and up hill pull. They are geared to high.

I have this setup in my '07 and the cams more than make-up for the tall gearing.  I no longer feel the burden of the tall gearing, even in 6th gear, as they boost primarily the low-end and midrange with some peak-HP increase as well.  I think they are excellent for baggers with stock motors.  CCP is such that they don't pair well with compression >10:1, but a stock 96 or 103 will be below that with stock gaskets.  They can also be commonly found on Ebay for ~$150 as CVO pulls, and that makes them a real bargain.

Most of those available on Ebay are low-mileage CVO pulls, and those riders simply want more performance that higher compression and more radical cams will give.  It's a win-win situation for both the buyer and seller if the buyer wants a nice bang-for-the-buck upgrade for a stock 96-103" engine without spending much money.  It in no way indicates there's anything wrong with the SE255 cams, as is readily apparent by the mostly consensus positive feedback from riders who have installed them.  I'm one of those and am giddy over the bump in useful performance I now have for my $285 investment, which includes the $93 Beatty tool.

I think the vast majority of those who denigrate the 255's--calling them "school-bus cams," etc.--have not ridden a loaded touring bike with these cams installed for an extended trip.  Sometimes it takes a ride and less scrutiny of the far end of the HP curve to clarify things.

And/or they tried riding the bike by spinning up the engine like they're used to doing with their "bar-hopping" cams or crotch rockets.

This thread has been somewhat derailed, trying to get it back on topic. Narrowed my choices down to following: CR575, SE204, Andrews 26H let me hear your opinions, or if you think I should look at another cam. Anyone got a dyno sheet for CR575 in a stock 96?

26 & 204 will reduce Comp ratio, the 255 will increase it 21will be the same as stock.

Don't Know about a CR575

Curious to know what led you to these three cam and why you think they are the best for your application. What are the factors that influenced your decision for these three cams?

The CR575, the heads can handle the lift and they have a 35* intake valve close for the power down low.

would there be any long term reliability issues with stock valve springs and the .570 lift?

There's plenty of 575's out there with stock beehives and T Man has a new TR600SM with .600 lift for stock springs. I'm not too sure on how well the .600 will last but I'm keepin an eye on it. I like that one..

It not denigration. It's affixing a proper label..

Ok You picked both ends of the spectrum. You next guess should be the right one..

Why not just go with a woods 5 or 5-6...?

Wasn't a guess and I already picked the right one.

coil bind might not be a problem,but spring pressure wont be enough @ higher RPM`s
