Ok so mabye Ill try this here. I have a 2001 ECSB 2wd with 402 LQ9, gt4508r 10 psi, 4l80, 29 inch tall Drag Radials, 4.10 gear. Went to the track and ran twice. 12.06 and a 12.02. 1.7 and 1.65 60ft. It feels like its giving up at the top of the rpms. going throught the traps at the top of 3rd at aroud 6k at 113 mph. Im guessing its feels that way because of small street cam. So I was thinking about doing 3.42 gears. Any thoughts???
