Grudge match

Well I'm heading back to the track on Saturday not really for any tuning but for a grudge match against a friend of mine and his 70 Chevelle. My car is tapped out anywhere from 12.00 to 12.20's at 112mph so cant pull anything out of the hat. His car is a 468 with ported iron oval port heads, hyd roller cam in the mid .500 for lift not sure on duration, pump gas, dual plane with an 850 Holley, 3 inch exhaust, 3500 stall and 3.90 gears , running ET Streets. Two years ago I didnt get to race him but driving it to the track w/o cooldown it went 12.48 at 113mph and no other passes, since then he has changed the intake and had it on a chasis dyno so now he's after me. Its kinda friendly kinda not because were both brand loyal and competetive. Well what do you guys think? Do I have a shot?

The one with the better light will win this one.Put some NOS on it and all he'll see is tail lights.8)
