rear tire size has a big affect on gearing, my N50-15 M+H is 28"

all depends on intended use...

had 3.91 gears and it was awesome around town and drag strip. sucked when i wanted to get on the highway and go places.

had 3.55 gears and it was a little better on the highway but still not great and it was still fun around town..

put 2.94 gears in the car and loved them.. still had enough bottom end to make the car fun around town and i could get up on the highway and cruise the way i wanted to..

jamies dart has the 2.94 gears in it right now.. probably put a 3.23 gear that i have in it this winter.

i prefer to go long distances. i don't have OD so i prefer gears better on the highway. but its all personal preference..

Hi Joe long time no see. Getting back to this subject, I am running 276 gears in the Dart, of course with a Blown Hemi I don't need anymore, it will destroy the tires under it no problem. With out an overdrive its tough to run lower than a 3:91. Like some of the Guys mentioned tire size, convertor and cam profile play a big roll in gear selection. To build an overdrive for one isn't too hard, but it takes money. My advice, sit down and be honest with your self as to what you want to do with your car. Outside of what I have mentioned this will be what will tell you what gear to run. A good all around gear is a 3:55, how ever 3:91 will work, but will make RPM at 60 mph and up.
