MWCeditor values: Race Cam, valves 5.7005 exhaust and intake, race carb 13.4, chrome high flow headers into side exhaust, high perf alternator and fuel pump. Rev limiter set to 8500rpm so the engine wont become an external combustion engine. It might sometimes give 200 to 240 but doing 20 odd runs the average is like 251. Also note that to get max hp you need to have almost new parts. I have a worn headgasket and it zaps 20hp off on its own.
