One of the guys on here you used to have a 3.8L on a 100 shot running mid 13s. Not too shabby.
If it is nice and runs good get it, however you can get a LT1 v8 for cheap, $3,500 or less.
And then he can spend the rest on Advil for the headaches it'll give him.
Seriously, if you want a V8 F-Body, my wife wants to sell hers. '96 Trans-Am, auto, ~135k miles.
