Timing with Hypereutectic pistons
And FWIW.... I have destroyed forged pistons with detonation caused by excessively advanced ignition timing in a race when the distributor got whacked. The hypers are a bit more easily damaged, but as Moper said, you gotta keep out of detonation with any of them. And you can detonate with any fuel and ignition system!
And as said, cam timing is not ignition timing. Advanced cam timing helps low end torque and raises DCR.
Pay very close attention to the ring gap info on the KB's.
