Which cams should I use for my /6. I have two different cam sets. I have E and S sets. I do not want to buy new cams. My car is simply for fun on the road. This is my general setup that I am building.
2.7l 70.4mm crank Stock 2.7l heads 9.5:1 JE 90mm pistons Dual zenith carbs. |

A one point increase in compression ratio (9.5:1) over the standard RS spec of 8.5:1 (optimistic) will increase low end torque as well as bring a slight improvement in fuel mileage. Some head mods might gain an additional CR (or a true 9.5:1), but the closer you get to 10:1 tends to require twin-plugs to reduce detonation with 91 octane pump gas. I'd opt for the S cams unless you just want around-town cruising punch.
