Which cams for my carbed 2.7 /6 build- E or S? Options

[tornik550]

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.

Like Bruce said, depends what you're doing with it. I went with E cams in my 2.4L MFI build. I have a 2.4S as well and it isn't as peaky as their reputation implies; it's okay for driving around town and fun in the upper revs. The larger displacement compared to 2.0 or 2.2 that the S cams built their reputation around, helps a lot to fatten out the lower rpm torque curve; your 2.7 will moderate the cam even further.

To me the biggest difference is where you want the torque when you want to "play". If you want to zip around town and have good torque stop light to stop light then the E is the right choice. If you only plan track days or back road bombing and don't mind that it needs to be over 4000 rpm to get into the power then the S will work. One question to consider is what rpm you want to spin your motor to. The S will require north of 7000 to really use it.
