ET difference from 3.91s to 3.54s

How many cubic inches are you running? I'm running 3.23's in my car, some day I'll try more gear at the track but I love these 3.23's on the street. It runs mid 10's but it is a mild 500" big block.
Very nice, how much HP and TQ is your motor making? Did you weigh the car? Mine is 3100 without me in it. i am hoping for an 11.60@116 mph with 3.73 gears
