I noticed that with my 3.55's, in 4th gear I am just about approaching 6k RPM at 100mph. A bolt-on 94-95 Cobra runs about 102mph trap speed. Most fast N/A 94-95's have 3.73's. Do these cars hit the factory rev limiter at the line? I have the 6k chip in my MSD box. Will I hit it before I hit the line if I got 3.73's?

I was gonna say... but 95snoozer beat me to it. I have 3.73's, and I'm nowhere near 6000 at 100 mph...

Same here. With nitrous, I am right at 6000 (and 116mph) going through the traps, but N/A I am barely at 5500rpm's (and 107mph)...
