I believe around 7.0:1 but im not totally sure. Displacement 3.12 makes for a very free spinning engine. I did put performance valve springs in it but i have set the rev limiter to 7000, the engine would love to spin higher. I used the stock 3 liter rods and had Supertec do the offset rod bushing modification on them which makes for a longer stroke.
Talk to Henry at Supertec about the 3.12 engine he can fill you in on the mysterious and powerful nature of this configuration....I sure like it.......
