Not enough compression ratio for the cam. You'll need 10.25:1 to 12.0:1 to make cylinder pressure.

Or, to put it another way, too much cam for the compression ratio. Here's a suggestion to get you in the ballpark. I'm not saying run right out and buy this cam, I'm just suggesting an alternate grind that would work with your static c.r., plus nitrous or a huffer. Read the description in the upper right hand corner. Always consult your favorite cam grinder for a recommendation based on your needs and your combination.
