I think Boogaloodude's explanation is very good, and you can't look at one value in a sea of specs and expect to know how a cam will run in a given environment. I'll admit my eyes go the intake close spec first, however, as that has become force of habit.

That's a bargain for someone.

That is a good bargain. I am looking at that cam seriously for my bike. I have also looked at the tw-555 cam. I almost never get above 4250 rpm so I would want as much on the bottom end as possible. I am leaning a little to the tw-555 based on some other threads and a dyno chart or two that I have seen. The price for used SE 255s or really good running around $100.00. I guess the question I would have is this "If the SE-255s are good then why are so many available as used?". I looked up the tw-555s and have not seen any used for sale. I might be putting to much into this line of thought and I should probably bite the bullet and get a set of the SE-255s based on the price but that little question just keeps coming up everytime I get ready to hit the buy now button. If someone can shed some light I would appreciate it. My current build is in my sig. Thanks.

I had my 255's in for about 4,000 miles before going 103", with the head work & added compression (10.2:1) the 255's were no longer the right cams for me. Installed Andrew's 54H cams and gained a little in the bottom end but, gained a whole lot of fun on the top end! Find I seldom use it but, I know it there if I choose to!
