6800rpms in 4th gear with 4.10's should take you to about 127mph...
120mph should be about 6400rpms in 4th...
120mph should be about 6400rpms in 4th...

Speedo may not be calibrated correctly??

Possibly...
Chris, did you use the white speedo gear or a speedcal to calibrate your speedometer?

After a bunch of highway blasts, I have decided I do not like 410s on the highway because I can no longer keep it in 4th gear. You have to shift into 5th at about 125, and that means if your racing at around 110 or more in 4th your way up there in the revs and once you shift into 5th, you lose ALOT of acceleration. Oh well, now the fun just stops at 125 lol instead 150 or 160 or whatever...I would not know

If you aren't ahead by 125 then you lost and should probably slow down because you aren't going to catch them anyways...
Besides, there's no point to going that fast on the streets...

basically, I run away from most, until the top of fourth, then it is about time to let off anyways, and then some of the cars pass me. But yeah 125 in a 60, and coming up on traffic, better have good brakes. just curious, I was told that I should still hit 154 in fourth, and thought because of bad vibrations, the car was looseing power. This is where a blower comes in to play right, and maybe some cams? anybody have any extra money? chris

Nope, with 4.10's you'll top out at 126-127...it's the way the gearing works, but in 5th you'll be able to go past 152 since the car will still pull in 5th with the 4.10's where with stock 3.27's it won't pull in 5th after a certain speed...

If I knew the ratio on your 4th gear I could probably give you an estimate.

I just used to like how with my 327s I could be in 4th gear going 120 and not have to keep my revs at 5k and more. Honestly Im too scared to shift into 5th at 125ish and keep my foot planted.
Oh and yes good brakes do help...I recommend powerslots slotted rotors and hawk pads.(nice improvement over stock)
