12-211-2 - Comp Cams 'Magnum' Hydraulic Flat Tappet Camshafts is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from Good street cam, but should use a lower gear ratio This is a great cam for the street with a decent idle, but one should consider a gear ratio of at least 3.42-1 and, if used with an automatic transmission, a higher stall speed converter. Also, taller tires will affect the final gear ratio. So, if you are running a gear ratio higher than 3.42-1 or tires much taller than the standard height that came on the vehicle, a 268-degree High Energy cam would be a better choice. The High energy cam will produce much better low-end power, while still revving to 5500-6000. The 270 cams don't start making really good power until 2500 up, whereas the 268 starts right off idle. The 270 is a great cam, if used in the proper application. However, more duration is less forgiving!

What kind of power gain will I get with this cam? Is there a web site I can use where I can put my info for my engine, what parts I'm using, so I can see what power gains or Loss I may have and be able to swap parts around untill I find the right parts?

Asked by: Joe Hampton
We would need to know more info about the application. There are several "desktop Dyno's" that are available on the internet.
