I logged into my youtube account today and ran across a video. Its a stock 2003 Express 5.3/4L60E and what looks to be 3.73s based on the shift speeds. It made my lack of gear very apparant. I need to get my 4.10s and Tri-ys installed. It would be very close 0-60 with me gaining an edge as my top-end hp took over. I alwayd wondered what my Express would have been like with 3.73s and the 60e. 30-90 wouldn't be an issue though.
