I'm hoping some of the resident experts could help me choose valve events. I'm trying to select a cam that way, rather than the more "traditional" way. I think if we work through the exercise on one pretty typical car, the methodology should be applicable to other combinations.
The parameters:
'02 Corvette LS-1, longtubes, hi-flow cats, CAI, otherwise stock. Pretty common case.
Stock, unopened shortblock.
Looking for peak torque around 4800, peak HP around 6300, shift at 6500.
Within that, idle quality is not important, and a broad power band is desired. Would also like to boost the low stock DCR if possible in the hopes of both better power and better mileage.
Comments from the experts as to what valve event timings might make sense? At .006, .050, .200, whatever you think is most appropriate.
