HELP! Thinking about switching from a XE to a XE-r cam My current setup is a 02 Z06 with TPIS headers, random tech cats, Vortex airbox and a comp cams 54-428-11 grind. The cam specs out at 228/230(281/283) with .571/.573 lift on a 112. It's ground on the XE lobes. So far the car has dynoed 415/388 at 6300 rpm and ran a 11.60@121.8 with a 1.89 sixty foot. My car also has a M12 tranny and 3.42 gears so through the traps it's only buzzing at 5400 rpm. I also ran that number in 80 degree heat. The car starts and run's fine but has the occasion messup when it starts to surge or idle weird with the AC on. Now I was thinking of switching to a comp cams 54-444-11 grind. This cam specs out at 224/230(273/279) with .581/.588 lift on a 114. It's also ground on the XE-R lobes. Do u think this cam will make just a much power but offer better driveability due to the smaller intake duration and the 114 lobe center? So what do u guys think?
