The only mod I could tell was a exhaust.

We went from a 20mph roll merging onto the freeway. The onramp goes two lanes into one then onto the freeway, I was behind him. At first he was pulling me pretty bad (3-4 cars)till about 115mph or so I started to pull real good. I gained the 3-4 cars plus some. I changed lanes to past him (still pulling strong) at about 130ish and got up to his back bumper then I ran into traffic in my lane and backed off.

I was real suprised that I pulled so well up top.

 

I am kinda surprised too, as you know the LT1 with just a couple of mods is a beast. My Buddies Impala SS waxed me pretty hard on 95 South about 2 years ago, but then again I didn't have to many mods and he had quite a bit.

 

I am suprised as well but, they do 0-60 in 7.4 and the 1/4 in around 15.6 @ 89mph or so. That is a perfect match for my Max.
