want to make 1250hp, but don’t want to do a deckplate? This is the solution!
-4.020″ bore but can be machined all the way to 4.250″
-OEM 6.7 deck height
-Cam oiling from mains has been shrunk from 7mm to 5mm for improved bottom end strength
-The thinner the wall, the less cylinder pressure you can run without failure 😉
-Hi-test alloy is 20% stronger than OEM 250mpa castings
