There's a broad spectrum of V6 Camaro's.. You're going to need to be more specific. I have no idea what size V6 motors the 1st and 2nd gens came with, but the 3rd gens came with the 2.8's, and 3.1's.. the 4th gens came with the 3.4, and 3.8's.. Stock, most V6's aren't fast, as they are designed for economy purposes. But any engine can be made fast.. For instance, this guy here:

A couple days ago he ran this in his 3.8L
60 --- 1.833
1/8 --- 7.6
mph -- 91
1/4 --- 11.78
MPH -- 115
The 3.8's are better and easier to modify, as they a larger aftermarket for them.
