Mopar 408 cam ??

I have never had my engine on a dyno but I did race it once. It was hard to launch the car due to lots of wheel spin but I was able to coax a 12.88 @ 108 mph pass out of it. This was with a 2.000 sixty foot time. I was shifting the car @ 5500 rpm and it weighed 3520 lbs that day. So with that info some of the h.p. calculators said that I was making 355 h.p. at the wheels to go that slow. That roughly translates to about 405 h.p. at the crank (depending on what % loss you use)
The cam grind that I'm running is from Bullet and it is # CRA 270/270-10HC
This is the converter that I'm running. https://www.summitracing.com/parts/hup-27-25hd/overview/
