Awesome deal springer. We got caught a bit too. Funny how tastes change and staying ahead of the curve doesn't mean shit when the curve changes. I sent back 4 110" kits because no one cared. Factory 110's? Who'd have guessed.

What is the feeling about including details along with cam listings, like valve lift, duration, lobe separation angle, overlap, single or dual pattern,TDC lift, rocket arm ratio, and opening.closing ramp aggressiveness? I would like to be able to compare cams by specs because I don't know them by heart (yet).

Here is a spreadsheet with cam specifications - this is a year or two old.

That was cool - translated it to Excel on the fly.

Check out our website. I have a cam comparator that has over 150 Twin Cam cams and over 200 EVO cams listed. I spent lots of time confirming the specs with manufactures. I found lots of bad info on cam specs when I did this. Many of the cam spec sheets had wrong info on them. Andrews was the worst. It was easy to see why so much info was wrong, depending on what spec sheet you downloaded from Andrews website you got different specs!!! Andrews cam specs on their site had some cams listed with 3 different sets of specs. I feel our comparator is the most accurate and thorough listing anywhere.

In the new future I will be adding a cam profiler. Comparing specs and profiles is the best way to understand a cam, the specs alone only show part of the story.


There are many other useful calculators as well.
