Here is the Cam I am putting in my Vortec Tahoe. Its mild with good power. It had been recommended. I will have it running by the end of next week.

Isky Cam RR-257/265-HYD

Duration @ .050
In = 209
Ex = 217

Lift with 1.5 Arms
In = .465
Ex = .485

Overlap 37*
LSA 112*

Whats your mileage? Im at 100k and my lifters are still high and tight. I have changed the push rods, gone to dual springs, and roller rockers. Magnafluxed the head, 3 angle job, new seals and machined the spring seats for the new springs.

I work around the corner from Isky's factory. So I was able to go into their shop and buy it directly.

You will also need a PCM tune. I am using Westers' but Nelsons or Wheatley will work fine also.

Their cam kit part number is 210257/265
It includes:
-Cam
-Pushrods
-Valve Springs
-Shims
-Retainers.

Summit has it
