I just got my 4.56 gears installed in my stock 10 bolt and it is great it compliments my 4400 stall great. I need to get the shift points reprogrammed because it hits the redline in 2nd because it accelerates so hard so I have to let off the gas to shift. It cruises on the freeway at about 2500 rpms in o/d.

It's a daily driver except when it snows here in ohio.
Torque,Torque,Torque! Torque accelerates,horsepower maintains.
I'm 'old school' from the 60s' when torque and gears ruled the streets.I've worked on rearends back then so they are not something to avoid working on.Back in the late 60s',you could get factory 4.56s/4.88s in your car order in camaros,novas,and chevelles.They were great 'light to light' streetfighters.So why not build a rearend for optimal 'light to light' streetfighting.I have 3 extra rearends(take-outs from f-bod),many gearsets(from swap meets and Summit 'discount returned items,2.41,2.73.3.23,3.42,3.73,4.10,4.56),various carriers(auburns,torsens,and eatons).
When I decided to take out the OEM 3.23 rearend(passenger side carrier bearing was growling),I figured why not build a rear with the $25 used richmond 4.56 gearset I picked up at a swap meet.That rearend was put in in sept. of 07 and I haven't regretted it since.1st and 2nd(with Nitto 315s on the street)are incredible.I've taken 3 trips to florida from cleveland,ohio with the 4.56s' and the computor has handled the mpg better than originally anticipated.24.5 mpg with the 3.23s,now 21.5 mpg with the 4.56s.No complaint here.Freeway rpm would be considered high,but I don't.It's designed to work in a range.Coming back from florida a few weeks ago,we hooked in with a fast traveling group on I-95/I-26/I-77 in South Carolina that put us in cruise control at 4000 rpm for a couple hours.The engine now has an incredible mechanical advantage over the car and it operates at a condition of not being under a load.

It is awesome I need a tune pretty bad so I wont have to let off the gas before it hits redline in 2nd so it will shift correctly. Driving it so far hasn't been anything crazy it just only has two speeds slow or fast nothing in between and with no muffler on it currently its pretty damn loud.
