I was just curious what the top speeds are for the most popular gear ratios such as 3.42's, 3.73's, and 4.10's. Just curious. thanks

gears really dont play a role un less you get real steep 4:30 and up...
other wise were limited by drag... we should all top out around 160-170mph! jmo

Depends on what your rev limit and tire size is. Also keep in mind you will be in 5th gear, not 6th, assuming an M6. With 275/40-17's, 4.11 gears, and a rev limit of 6750 rpm, I have a theoretical top speed of 173 mph with my SS. I have an official track speed of 161 mph, but had some throttle left at that speed. You may be able to go that fast with 3.42's, just at a lower rpm, and probably need to be at close to sea level if running a stock LS1. When I went 161, I was on salt and at 4500 feet, both of which slow you down 15 to 20 mph.

why cant you have it in 6 gear for top speed

2 SLOW

it is a really high gear and cars don't make ebough power to accelerate with in it

Thanks for the responses.

I have 4.10's, a 6200rpm redline, 18"rims. I do exactly 154@6200rpm in 5th thats 4100RPM in my 6th, 6th will accellerate a few hundered RPM I was able to get to(with headlamps up and TTops off, windows up) 4450RPM. I think it is at the 170-175 mark, I looked it up on Randys Ring and pinoin page. 6Th isnt that bad. I have accelerated in 6th from 80mph(2200rpm) to 4200RPM let off due to room to run.But no slouch, as fast as a modded Lighting from 120 up while in 6th, and my lightning dies out @ 149mph.
