its going to be a virtual toss-up if he's a 5 speed. An auto is a little slower than a 90-92 305 TPI auto car. Both are low/mid 15 second cars.

Yeah, those new 4th-gen 3.8 V6's give out some pretty decent power! Heh, they can actually beat the new Mustang 4.6 V8's... what a kick in the butt for Ford.

I have driven a 2001 4.6, and there is now way a 3.8 Camaro is out running it. Maybe the like 97 4.6's that were dog slow. Not the new ones. Im sorry but they are a lot faster with what ever they changed on them this year to give them a few more ponies.
