Re: Gearing suggestions for my LS swapped truck
3.42 is not much of a change from a 3.08....my 13 gmc has 3.42s and its always downshifting....my 99 chevy has 3.73s and doesn't have the shift issue....
your 3.08s with a worn set of tires will add about 100 or so rpms at 65
3.42s will only be 183rpm increase over your 3.08s at 65...3.08=1652rpm....3.42=1835rpm
my 81 6.0 has 4.10s turning around 2100 at 65....and I love it...
bottom line its all in what you want.....
