(superstroker) Roby spokane wa internal parts of engine faulty, had to replace cam bearing,cam, lifters and push rods, to include exhaust valves spokane Washington
I purchased the engine two years ago. Since then I replaced lifters. Got a dyno check with horse power 215 240 twice. A couple of months ago had the heads removed to find out exhause valves were moving from side to side. two push rods were bent and three rockers were damaged. They were not roller rockers. you could imagine the cost.
