UPDATE: forgot to post this. Was digging around in the street scene again and found this Camaro kid has never taken the car to the track, just street races, so I don't know what he was running in the quarter. However, one of the mechanic friends of mine (with the 1500 WHP TT F-body, now broken) was around when the Camaro ran a GT350 Mustang "with headers" and possibly a tune (we didn't get that far before other things happened). And, if I understood this guy right, the 350 was beaten by 3 or 4 car lengths. So that works with my estimate that I gave them about .5 to.75 seconds head start and overtook at almost the quarter mile mark.
Would almost like to go out and run this guy again, under more controlled circumstances.
