Wondering what gear ratio to run?
 

I have a 69 Camaro with 2001 LS1 T56 combo and 335 30 18 tires mounted on 12" rims. What gear ratio should I go with? I will mostly be driving around town and highway cruises with the family and not out racing.I was thinking either 342 or 373. What do you guys think??
thanks

I'd go 373, 6th gear sort of lugs with 342 unless your buzzing 90-100mph. 410 isnt even that bad.

I'm not sure about the Chevy rears, but if you are using a 9" Ford the 3.89 is a good choice with an overdrive tranny. :thumbsup:

3.89-4.10 ls motors like to rev. and with a 6sp you have plenty of overdrive.

I'm running 3:73's in my Nomad - Ford 9" - 700r4..... 26" tall tire.... LOVE the combo

Just changed to 4:10 from 3:90 with a 315/30 18 tire. 6th is comfortable at 70-75 or so. I like it so far.

if your cam has any lope at all, 3.73's with 26" tires and 4.10's with 28" tires.

I have 3.73's with 28" tall tires and 6th bucks at light throttle below 70 mph behind my old school 350. of course I have rhs vortec heads on it along with the small comp thumpr cam. I'm going to 4.10's in the next month or so. a 4.30 was actually my first choice but they are not available for 3 series 12 bolt carriers.

I'm running 3.73's I wouldn't go any less, LS motors like to rev.

correction, after crunching the numbers, I'm going to go with a 4.56 gear this time. my 28" tall tires have everything to do with this call. yes, I took the driveshaft critical speed into consideration and I am safe.
