Predator is right there's definately a lot that goes into spec'ing a camshaft. That's why we work so hard to test so many different combinations & occassionally a few competitors camshafts. It's amazing how many times I've heard a camshaft is the greatest thing on the internet only to find that it makes no more power than a well setup off the shelf camshaft.
Custom designing camshafts is a great option as long as your taking advice from the right people. You have to ask yourself how many camshafts do I think these guys have installed, how many camshafts have these guys thrown across the room because something should have worked, but it didn't. How many times has these guys installed a camshaft back to back to see the true gains from making a change.
It's really easy to sell camshafts on the internet when you don't have a dyno to prove what your saying. We work to provide camshafts that actually make proven power. I'm very proud of all the testing we do, this insures that the customer buying our camshaft gets exactly what they expect & not someone's best uneducated guess.

"The larger pushrod test is coming next week."
I'm really looking forward to this test. This should be quite interesting. People who have run the Spintron say you should use the biggest pushrod that will fit. I would be interested in the difference between a 5/16" and 3/8" pushrod.

The MS4, Tsunami, & the TQ3 produced very good power, but they are all reverse lift cams. What would be the difference if you put the MS3 cam in there, which doesnt have a reverse lift? Would it be possible to put the MS3 cam in on that same dyno and post some numbers so that we can compare them? ...or are the cams with reverse lift produce better power?????

Jason and Texas Speed Crew:
First off, my utmost respect to you and your professional engine tester crew at Texas Speed. You have accomplished a quantum leap in cam testing.
You have to understand that you will always have doubters. Anytime you challenge people who hold such strongly held views and preconceived opinions, you have to expect the occasional negativity.
With the utmost respect, I would choose to not take it personally. From the response of many LS1Tech members, so many members are hungry for new information.
So please don't withhold your results. I and many others have been very loyal customer of Texas Speed, and I think your business will continue to grow as a result of your leadership in cam development.
I would respectfully suggest that if given the time, and with the further help of some expect Excel or website 'experts' to help organize the various cam results in a more user-friendly manner.
Several users have presented some interesting graphs of HP/TQ, but without being unduly critical, it is a little hard to immediately decipher the results.
If my computer expertise was greater I would volunteer. And I realize it is very early in the process.
Anybody have some constructive ideas on how to display a more 'user-friendly' way to highlight the test results?
I think the graphs can be helpful, but I am just humbly suggesting that there must be a more 'user-friendly' comparison method that will really make potential customers immediately understand which cam may for them.
Again, my utmost respect to your company taking the lead and sharing your results.
A lot of interest, and along with myself and many others, we will be very interested customers.
Again I mean this is the utmost spirit of positive and constructive feedback.
Thank you very much.

It get tricky with so many Intake, Heads, Exhuast, etc variables to make good use of the data. But it would be a start.

Were 1-7/8ths --> 2 inch the only dyno headers available? It seems you would have had better numbers all the way across the board with a stock long block. I look forward to seeing the pushrod test. Any way you could throw in some dual taper pushrods into the test?

We aren't planning extensive engine dyno time like we did here for a little while. "Reverse lift" cams aren't magical. They just have more aggressive intake lobes than exhaust, which has been shown to make more power under the curve.

dont forget this is an engine dyno, no power steering pump, alternator, ac-compressor, perhaps even an electric water pump, large stepped headers, and probably no cats, low coolant temps etc etc not to mention the 92mm fast intake
