Thanks for all the support guys. The engine was actually set for 165 to start the pulls. The temp isn't accurate on the sheets

damn you gotta love an ls1's power curve. even the stock motor is impressive.Jason, was that a fast intake used for these test? in your findings , how good is a 6.0 truck intake compared to say an ls6 or a fast? I have to start with the 6.0 on my nova untill my budget builds back up .
Nice to see how the MS4 faired, even down low - hopefully the small cam crowd will take notice.

Yea we slapped a DOD pump on it before putting on the QTP timing cover as some cheap insurance. I had that pump on the shelf in the shop since we don't like using them.
DOD pump and 30wt oil = very high pressure, I expected it to be closer to 90...
I wouldn't normally recommend that pump but we had it and had no other use for it, in the end this is still a cheap stock shortblock, if we cared about the longevity of the engine, we probably wouldn't have made 72 dyno pulls with it anyway, lol.

Towards the top of the graph it seems fairly typical that the bigger the cam gets it produces slightly more power than the one before. What surprises me is that the "smaller" cams dont outpower the "big" fella's low and mid range.....
Also there is alot of difference between a 228 cam and a 244/248 when it comes to tuning and drivability, but not such a huge difference in power output, is 21 hp worth it in a street car?

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.

If your looking for stock like streetability then go small...larger cams are very streetable...I drive mine all the time and it has very good street manners...it's all in the tune!
P.S. I love this thread.Thanks Jason for all of the work that you guys put in to provide us with good viable data.Please give us some numbers in relationship to the dyno pulls with the various heads strapped down on that mule of yours.
