Call Dan Cragin.
Larger cam is not always better.. And, it should be closely aligned with other variables, such as the compression ratio, specific use, etc. I think Dan actually wrote in a thread here about that very topic not long ago. Use the search feature for his posts (user name: "Dan Cragin"
Consider getting more out of a cam with rockers with 1.7 ratio.
Consider Stryker heads, if you can find them. More expense but more power.
Greg Good is considered a top-notch head-porter. Multiple threads seems to indicate that he'*****-and-miss though (Doesn't return calls, long lead times, etc). I decided not to go with him after some discussions, but his work is supposed to be great.
Also, Vipers are known to have various cam degrees from factory. And, there is no way to adjust it unless you install aftermarket parts. This is labor intensive but a must to get the most out of a cam.. heck, to get the most power when tuning the car with any mods..
Again, Dan is the man, a call to him is a very good next step.. And, you can't go wrong with having him do the work.
