SS LT1 motor? I was just wondering if there was a big difference between them.
The main differences between the 9C1 LT1 package and WX3 (SS) package are the green silicone hoses in the 9C1 and the PCM programmed speed limiter settings [based on factory installed tires]. The SS came with better tires and therefore has a higher speed limiter setting. This can be easily changed with custom programming.

The differences between an F-body LT1 and a B-body LT1 are significant. The heads on the F-body are aluminum and the cam is set up for more top end power and gives up a little low end torque [bad for our cars]. The F-body PCM programming is more agressive and requires higher octane fuel. Again, speed limiter setting is based on factory installed tires. There are also differences in hoses and routing, air boxes/baffles/resonators, and [I think] accessory placement.

I had always thought there was a hotter cam in the 9C1, I did not know they were totally the same... You learn something new every day.

Nope. Chevy gives it higher performance models a red "bowtie". There was a big hoopla over the Impala SS not getting a red bowtie when it came out, but the only higher performance items were a better rear gear (3.08 in the SS and LT1 9C1 versus 2.93 or 2.56 in the other b-body cars), rear disc brakes (in the SS and 9C1), and better tires (Z-rated for the SS)... not enough difference to get the red bowtie.
