Need cam ideas for my 318 Duster

Hmm, not what I wanted to hear lol. Well, I do actually have a complete used nitrous system that I've never used...

Getting enough CP is the challenge. I know. 63cc is what they say, but I haven't measured them so can't say for sure.
Wallace calculator doesn't fully agree with yours, or do I miss something? With this:

HUG STL3842AS-8​

Hughes cam I get 186.8 PSI with 9.6:1. Or I'm I lost in the math?
Hughes Engines


I have started to lower them already. And thinking of adding that nitrous system LOL.
Nitrous....cheap horsepower
