360=500hp

like adam has writen you will have to turn real high RPM to make 500 rpm with a stock stroke engine to make 500HP i have a 340 wich is about as hot as adams but it has a rollercam and that makes it alitle stronger from low rpm but its still nowhere near something i would recomend someone to build as a daily driver engine... sure it can bee done but i would go for more cubes wich makes more torque
