BTW Dynos only measure torque. HP is a mathematical dirivative or torque over time.
HP=Torque times RPM divided by 5250 So all engines will make the same horsepower as torque at 5250 RPM. The abilty to sustain torque at a higher RPM will generate higher HP levels. IE 10500 RPM the HP will be 2 times torque.
Also, V twin Harleys are dominating NHRA Pro Stock MC two valve v twins vs four valve 4 cyl
Just because we call it a stroker, the reality is it is just a 455 with 3" mains and 400HP 500TQ out of a stock type 455 is pretty good.
