You are going to have trouble outrunning th 041 cam with the 2802 no matter where you put it.

I've dyno'd a completely "stock" 455 with untouched heads with 96cc combustion chambers in them and it made 440hp and 530ft lbs torque with over 500ft lbs torque across most of the loaded RPM range.

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......
