Your Camaro should be high 11's car. My friends 4400 lb 300c show car makes 440 whp and does 11.9-12.2 @ 113-114 mph..... without a stall.
As for the vette, they really aren't all that fast.... In my heads/cam ls1 Camaro I had a close race one time with one, but on the top end I started pulling away decently. They are mid-high 12's car, the fact that he is manual almost guarantees you win unless he gets a perfect run in.
