I see:

Shifting at 7500-ish rpm if you have good heads, especially with the nitrous.

The lobe separation is tight if you want it to be a "nitrous cam".

I have thought a lot about this.
I want a N/A engine that I spray once in a while.
To use a wide separation for a once in a while shot may not be the best plan.
It is a small flick when compared to the size of the ci. It's not like I'm dumping buckets of the
juice into it.
The engine is primarily a MAX power for my bracket car.
And if buddy ever sells me his original C8 Tunnel Wedge
then the cam should work good with that intake.
I want to spin into the mid 7k's so I don't have a problem with that.

Well I think you're on the right track then.   I just got the 3/4 race cam joke.    

A 4.56 rear gear will get you around 135 mph at about 7400 rpm with 28 inch tires.
