want to make 1250hp, but don’t want to add mass or do a deckplate? This is the solution!

-4.020″ bore

-OEM 6.7 deck height

-If running High tensile, alloy we suggest DLC coated Toolsteel Total Seal rings.

-should be honed with diamond hone.

-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 😉
