3.23 or 3.55?
Short cruising , this mean highway ? Cause 2.76 in the city will be a dog , 3.55 is a good all around choice for city /highway/strip , on the highway I'm buzzing 3300 rpm at 70 with 3.55 , 235/60-14 tire , not that bad , 3.23 will bring me 76 mph at 3300 rpm. Not a big deal . 3.55 is the best compromise gear imo .
All I need now is traction !! All my car does is spin through 1st and a bit of 2nd gear , your 400 hp 318 should do the same . .
