A while ago I made this spreadsheet comparison of the OE vs C&B cams. Full lift on the intake cam is in a different position. Having never seen the locking tools I'm not quite sure how they work but I would agree with mattB that you might not be getting the best out of them by using OE timings.

NB the figures aren't completely comparable between OE and C&B because of the way in which different companies measure/quote their specs.

Hi,

About the C&B cams, there are plenty of things, which doesn't match with them!

Look the specification posted by MattB, it claims that intake variator changes timimg 25 degrees!! Only 18 degrees in Coupe.

Then Fiat informs the timing values by 0.45 mm lift. They match exactly with our measurements. We received Intake/224 deg and Exhaust/223 deg.
Now the C&B with same 0.45 mm lift to be able to compare them with OE cams.
Intake 234 deg and Exhaust 228 deg!!

We also made a test with Intake cam and 0.15 mm lift, with that the timing was "only" 247 deg.

In any case the C&B cams makes a good improvement in reality and we are pretty much satisfied .

The C&B timing in our cars are not even a close to OE settings .
