What I cannot say is how/what the 200 N20 charge will be doing to the engine's peak combustion pressures. It may be fairly well on target with that.
Without N20, the engine with that cam will have a DCR of around 7.2, even with the .027" thick head gaskets. With 5 degrees of cam advance, it is still in the 7.6 to 7.7 range. 7.2 is like a stock 318 DCR.....
That is a pretty lazy cam and it not meant for low RPM torque when normally aspirated. Better be ready to do some revving!
