BOBO,
Here's the Crane cam info for you:
http://www.cranecams.com/254-255.pdf
Both my engines use the 359351 profile with their lifter, pushrod and spring recommendations. Fifteen years ago this was their most aggressive profile, and since as engine size gets larger, the bigger cams seem to act tamer than they would in a smaller engine, so I selected this profile.
I heartily agree with the above info about making sure everything matches in the valve train.
Since the Cobra is fairly light, I ignored their recommendation for stall speed for my C6s; I use 1600-1800 in each car. Don't know what it would do for the drag strip, but it helps keep the heat down on the track, and makes highway driving less of a chore. If you use a stick shift, this info is irrelevant ;-)
I use a 6000 redline when I'm on the track (as if I really need to but it keeps the rev limiter from going off as frequently) and 5500-5800 for the street. The power is always enough for me in either circumstance - you may have another perspective.
Pushrod angle was thought to be a factor - it hasn't been for me (yet)...
Hope this helps,
Tom
