I agree with CustomChrome. I ran a 4 speed manuan tranny (1:1) 4th gear with a 3:73 as a street car and wasn't happy with it. It would have been fine as a weekend driver. I changed to an O/D tranny and am very happy with the 3:73. If you have questions about RPM's with your tranny and rearend, check out this site. When you type in the site, make sure you capitalize Gear, Tire Speed, and Calculator, or it won't come up. <a href="http://www.mtv411.com/auto/Gear-Tire-Speed-Calculator.htm" target="_blank">http://www.mtv411.com/auto/Gear-Tire-Speed-Calculator.htm</a>

I must say that I am happy with my 65 Impala 327 with 411s and a overdrive trans. Even with the 411 gears, it still gets better gas milage on the highway (runs lower rpms) than it did with the stock powerglide trans and 331 gears.
I would urge you to go for the 411s and get an overdrive/4speed trans. |

I agree with these guys. It depends on the tranny. If you have an overdrive go with 411's if you dont go with 373. The reason for that is that when you have 4.11 the tranny will give you 4.11 up until the over drive kicks in then the ration drops to a 3.73 that way you will be satisfied on the highway. If you have no overdrive and you use 3.73 then your tranny will be on 3.73 throughout all the gears. So my suggestion 4.11's if OD if not then 3.73

I had a 4:10 in my 34 Coupe with 700R(O/D)and it shifted to 2nd before I could get out of the driveway. Ran a 13.9 99mph and was over the rev. Changed to the 3:73 and was much better but think 3:55 would be the best. Ran 12.9 104 with 3:73. Strokker 383 tacked out.

Hey Eric, It's good to see U know where the real gearheads hang. Anti-rice is cool, too. Sometimes your boys get a little distracted from cars, tho'. Ya, I know, it happens here, too. O'ya, I totally agree w/CustomChrome on the gears. My favorite overall is 3.91s in a 9in locker. [ March 15, 2003: Message edited by: kitkar ]</p> |

I've got a '77 Camaro that was converted from an automatic to a manual. It now has a Muncie M-21 and a 2.76 rear end. I drive this car daily and some on the strip. Should I go with 3.55's, 3.73's, or 4.11's? I like 3.73's and my mechanic and friends agree.
P.S. If 3.55's are the best, where can I get some for a 8.5" 10 Bolt rear, or will I have to change rear ends completely? Thanks for any help |

I say go with 4:11 if you have o/d, if you dont then you will hate them. I have 4:10s in my daily driver, but I have o/d and can cruise on the highway about 2,200RPM. You will love the 4:11s out of the hole.
