Congrats on using MVA to give your engine the idle timing it wants. Once again in this thread, we see the IGNORANCE creep in about idle timing. By running ~30* at idle with that cam, your engine will have the smoothest idle it can, use the least amount of fuel, run cooler, & is less likely to have an off idle stumble [ because the engine is making more HP with MVA & can carry
the increased load as you give the engine throttle ].

This engine had this cam: 197/212 @ 050; 113 LSA. Comp Ratio was 10.75:1. Pretty mild cam, right? It is how my GTO left the factory & it idled at 26*. 6* init + 20* added via MVA.
Bigger cam & lower CR, suddenly 30* at idle is not too much......
