What's the best street gear for 489 case

[m99roadster]

I would like to put 323s in my 68 Dart but I'm having trouble locating them. Would there be a major difference if I used 355s? The car will be used for cruising around town and on the highway. The rear end is an 8.75 with suregrip and a 489 case.

yea i don't think anyone makes new 3.23 gears...


personally if its just going to be used for a cruiser i'd go 2.94 gear.. its a great gear. loved it in my dart.

3.55 are a great all around gear and in the middle of acceleration and fuel mileage
Also depends on which size tires you are running.
