At the track my 100k 100 Z-71 Smoked a Dodge rcsb's time. Then raced a new (under6000 miles) ecsb Chevy and put about .7 sec. on him. mine is pretty much stock except for a Hypercrap program ( that actually slowed me down) LS1 fans and free mods. He didn't really have much eigthor though. On the way home I got up beside a ec with the escalade front end and from about 85 or 90 we rolled on it I just couldn't keep up. He kept putting his hand out the window signaling for me to go. I just couldnt. Oh well Just wait for the real tune exhaust stall and cam then I'll have his ass? If not
