So I talked with Cam Motion and gave them my build info and this is what they want to grind for me.

115 LSA, 110 ICL (115+5)*

Looks like it has 6.5 degrees of overlap. Should work better with your setup.

I told them to go ahead and get the process started. Will this cam still have a decently choppy idle? I'd like for it to still sound like it's cammed.

Yes it will still sound like it has a cam.

Lol, I know that. I was just curious as to how much the 416 will swallow up the smaller cam. This is what it sounds like now with that huge blower cam in it. https://youtu.be/DBPGMN6MlwU

Just ordered it and after talking with him and him finding out my motor was a 416 he went to 236/242 Duration*@ .050''

236/242 Duration*@ .050''

9 degrees of overlap should still sound choppy even in a 416.

Got it installed and the car runs so much better, even without messing with the tune yet. Normal driving is much easier and partial throttle pulls feel great and the power is nice and smooth and the boost feels like it comes in smoother and a little sooner. Can't wait to get the tune touched up and see what it can do, it feels like a different car.

I like Cam Motion, and agree with what you did. Now if you get aftermarket engine mounts you will know what choppy is. I like the feel of the afermarket mounts and cam, it does also free up HUGE room I assume needed for twin turbo.

that cam is much bigger than mine. New Era Performance and CSP specd my cam and ended up with almost exact same specs. idle and drivability is amazing and makes great power everywhere

.635/.635 116+8
220/228

Good to hear!

Isn't yours a 378 though?

You being twins and 416 you can get away with more overlap, not that back pressure issue like with the single. How's the car running and do you like the intake ?
