This was a 1/4 mile? Looked like that. That being said, the Gen 1 was only 1 truck length behind. That's like .2 in the 1/4 mile. I don't think the gen 2 is anywhere near 600 hp. Infact people are getting into the high 13's with stock GEN 2s!!! Even the whippled Gen 1s were lucky to get in that range. Bottom Line Gen 2 stock vs Gen 1 stock is a BETTER performing truck all around, with the exception of sound performance.
Plus the true potential of the truck is unlocked after the wheep hole is drilled. In fact, an inside source tells me THAT'S ALL HENESSEY is doing to get 600HP out of the GEN2 and charging 20,000 for it.
