You people dont even know the start of what a DSM engine can withstand. 1000whp stock untouched blocks. A stock head DSM, by stock i mean stock portwork and even stock valves has seen sub 9 second passes at over 160mph and 900whp. A set of cams and a set of springs/retainers and you have a head that you can twist 3k rpms past the factory rev limiter (factory limiter is 7k).
