[74Grandville]

in my opinion you're going about this a in a way that will not give you the results you want. sounds like you were happy with the old, much smaller cam. your gearing is also not ideal, let alone having a gear vendor unit. your engine will be cruising at an RPM range it will not be happy with. I think most say to install a RAIV around 110 degrees ICL for best results. You would use the advance/retard settings in the chain to put the cam where it should be using a degree wheel.

for example, even if you advanced the 041 to 105 ICL (8 degrees). it will be down in power everywhere compared to a high lift 744 (summit 2802). especially low end torque!
