i have 2014 Muscle Machine magazine 418 stroker build.
340..4" stroke,Hughes hydraulic roller .520 / .544 and 1.6 roller rockers
9.3:1 compression.Pocket ported x heads,stock iron intake (which are probably holding it back some)
dyno numbers were peak hp 347 and peak torque 425
i also know 2 guys with warm 408's that were 375 hp and 450 torque
...don't sweat the hp number strokers make torque
