I found this on ebay today, guy says 400hp and 12.3 second 1/4 mile time. I'm not in a position to question since I'm a newbie and haven't modded these cars so I was just curious if this guy's car sounds capable of the mentioned power and times. In case the add gets pulled or expires, here is the text from his description:

well its weird that he has the 4t60 trans only because all stock gtp's event the 97's come with a 4t65e. the car must have started its life as a GT and was swapped...but with that mod list it looks like he can be running in the 12's.
 
i see rockers, intercooler, gen v, headers.

Thats 12's with the right driver.

Little lost on the pulley size though.
 
Also whoever repaired it from the accident didn't do a nice job with the hood gap. I wouldn't go for it, there is a reason(s) why its at $1900
 


i also found it weird why he stuck with the stock cam. if youre gonna go all out might as well cam the damm thing
 
with slicks i could see the time slip as plausible.

rocker cars aren't that bad, but most people don't have their car tuned for **** and need more than what it really takes to get there. example: everyone with a non-stock supercharger pulley running 14s.
 




it runs drives and boosts no knock 17psi. have not gone to track yet just finshed fixing couple things on it. is there id plate on the trans or something so i can look ?
 
The 4t60s are vacuum controlled, if you see some vacuum lines going to the trans then it's the 60 not the 65.

And no noticed its meth injected?
