*Piston will NOT fit into stock engine without clearancing the combustion chamber. This piston is designed to be very effecient with tight tolerances, so to order this piston we will need you to send your head to us so we can machine the head out properly.*
 
This piston provides power gains across the entire powerband. This is the piston that we run in all of our 450 race engines. This piston does not require a mapping change to run properly, but we can remap your ecu to match your setup for best results.
