It might sound like overkill, but I think it makes for a long lasting investment that way and is probably a little better performing engine too. I also took time to have the carb tuned properly for the air in my area. It hammers and I'd do it again with Roush. Most my driving is around town for a cruise, but it definitely is a performer. Thanks Roush

It's not overkill at all .. high oil pressure on a cold engine equates to a reduced oil flow, due (mostly) to increased viscosity. I never exceed 3000 rpm, and it's a very light pedal to get there too, until my oil hits 120 deg in my Z06. It's 140 deg for WOT.. In fact, I just installed an oil temp gauge in the Cobra for the same reason. The Pond 482 would be more expensive to replace then the Z06's LS7.. It's not only the reduced oil flow issue too. It's also that the engine clearances haven't reached "spec" yet too. This becomes even more important w/an "all aluminum" motor. I think you're spot-on with your precautions.
