SE cams

what year is your bike? Do you have any other mods done so far? I just installed the 255's in my 08 and they really woke my bike up. I have rinehart slip ons arlen ness air cleaner and run a power commander. I have also just had bike dynoed by Rob's dyno service in Massachusetts. 86.3 hp and 99.4 foot pounds of torque.

What engine do you have? Is it stock?
Also there are lots of other cams out there that are not HD smog cams, much better made than the HD cams, and that can apply the torque where you want it applied. Staying with a Screamin' Eagle product thinking that it will preserve your warranty is, well, not always the case. Anyway, do a little research to find out what is best for your setup. Lots, and lots, and lots of cam threads.

As for the alleged worthlessness of "EPA-compliant cams," remember that the cam in a 638-hp ZR-1 Corvette passes all EPA regulations, so this status doesn't necessarily translate as worthless or compromising. The important thing is how they run in a given environment, and if they provide the needed performance improvement while also being environmentally friendly compared to something else that shouldn't bother anyone.
I don't think the model number of SE cams (high or low) has anything to do with their characteristics.

Instead of "which cams give the higher torque?," for me the better question would be "At what RPM is the torque realized?" If you have a high torque number that is realized at an RPM where you don't normally ride and is low where you do ride, you may find the effects less than pleasing. I would read as many of the cam threads that you can for help on this topic, as there are many with lots of good feedback.

I'd agree with above advice and also suggest to the OP that he read a lot of cam threads before buying. Lots of people recommend cams and have no clue why the cams perform as they do. Once you can look at a cams specs and understand what kind of performance it will give, you are ready to do your cam job.

Another thing to remember/think about when comparing Harley cams vs the aftermarket cams. Nobody has the pockets (Think research) to develop camshafts for durability than Harley.
Sure, aftermarket cams can and will give you more power/tq, but if your looking for all out power maybe a Harley is the wrong bike to ride.
YMMV

I know some very knowledgeable techs who think very highly of SE cams. I've heard them remark that they perform well in the proper environment without objectionable side-effects, like valve noise, and other woes after installing them. I wouldn't hesitate buying another one in the future, but I don't race my bike and just want it to perform at its best where I ride.
