MHS / Wiseco Gen 1/2 5.0L Coyote Competition Piston and Ring Kit- 3.650" Bore, -3cc Flat Top

This MHS / Wiseco Piston and Ring Kit is designed for competition use and capable of relabiably holding 2500+ HP and 45+ lbs of boost. These Pistons have many subtle upgrades and details that make them just plain work! 

3.650" Bore - This part number was originally designed to be a replacement for our 3.630" Bore Pistons. If you are starting with a new build, we highly suggest starting with the 3.630" Bore Pistons and using these for the next time the engine block needs to be serviced. 

Why 10:1 Compression? It's a good compression ratio for high boost pressures. There is no need to go any higher, just to have to pull more timing. We have had extremely good success in the 10.0:1 - 10.5:1 Compression range on both Ethanol based fuels and Methanol.
