I have recently built a stroker motor from a 351W with a Scat rotating assembly for a 408(actually a 414 because it is .060 over). The kit came with Keith Black forged IC750 pistons.
I assembled the engine using ProComp CNC Aluminum heads with 2.02 intake and 1.60 exhaust valves.
The valves are hitting the pistons at the top of the valve reliefs. I would have thought that the pistons would have had big enough valve reliefs - since they are designed for a stroker engine.
I contacted the piston company, and they said it had enough material to cut the required opening - but not to get to close to the sides of the pistons(because it could get into the top ring).
I will clay it again - because I am concerned about the side clearence also.
Has anyone had a similar experience?
Thanks
Joe
