Folks are paying a lot of money for heads that Are capable of making that kinda power Most 408's aren't making that with a factory port design at least
I seen a lot of dyno numbers that say they do but not very many time-slips
To back it up

First of all most 408's don't RPM like a stock stroke will. Second--this car is very well setup and fairly light drag car. J.Rob
