6.4 cams

Is that the cam making the idle sound so raspy like that?

People say my truck sounds amazing... and I attribute it all to the stage 2 colt cam. Lol.

Pistons.... That's a 40* or so cold start. It starts up smooth off the glow plugs then will start running like that once they cool off. Clears right up once it gets some heat in it.

It's fine... Idle smooths out and smoke goes away by the time I'm to the end of my driveway.

The smoke isn't nearly as bad as that video makes it look, my phone did something weird with the lighting.

There is no reason you shouldn't see an increase in HP, if the cam is designed properly. I will be curious to see what Chris and Side Action come up with.

We have done a cam only swap on a 6.4. Using our Stage 1 cam. No other change, dyno was done before and after. The power change was minimal. We made 18hp and 50 ft lbs of torque. These were not peak gains but low end gains. On the top end the truck had less backpressure.

Josh, what's your stage 4 worth?
When you say "Optimized valve timing" what did you change?

i'm moving from the cam i have, to a RCD stg 2 cam. motor is done, waiting on lp turbo to get back from getting a 360* thrust put in.

the rcd has a little more lift and less duration than my current one, and my current one has a extra 6* of lobe separation to help drive the turbo's harder so we'll see.

if your curious about the stg 2, i'll be able to give some info in the near future.

stock fuel, ******** tunes, rcd 75/59, lowered compression 1 point.

i had uppipes leak, some rockers that were trash, and some other odds and ends, so we went to bd manifolds and rcd up pipes, and a rcd cam.

no, there will not be dyno sheets, just a tree trimmers opinion of a cam.
