Thinking outside the box

I think NHA has always put Mopars at a disavantage the way they rate HP. I just sold a set of virgin X heads to a guy who is running a 69 Cuda in some type of stock class. They rate his car at over 300 hp. He tells me the 350 Camaro's are rated at 255 HP. Which means they are allowed to run lighter cars. He has to add weight. Not fair in my book!
