I've also street and track tested the RAIV cam in a 455 with 6X-4 heads at 109ICL, 111, 113 and then 107. The testing included idle quality, vacuum production, street manners, then backed it up with drag strip runs. It likes to be at 109ICL and ran nearly as well at 111 but just a tad "soggy" right off idle for normal driving, and just tad slower in 60' at the track.

It HATED being at 113ICl and remarkably, despite what folks tell us about "advancing cams for more low end torque" it was a "turd" at 107ICL as well........FWIW......

Yes anything can be overdone, like advancing the cam. But unless your cam had a 109 LSA installing it @ 109 ICL most likely had the cam installed in the advanced position.
