EFI don't care what cam you have, only a bad tuner blames the cam. I run solid rollers, 280 at .050, and .750 lift
Even according to the techs at the different EFI companys they all said that the wider LSA is better... that way you dont need the electronics to try to cover up.. but the narrow cams will work... on my Holley.. it changes loops at 160* so that is a while even with a stat(I have 4 1/8" holes in the stat to move water at all times due to the elec pump)
