63 impala ls2 & rear end strength
I got a 1963 impala with a ls2 motor 4l60e trans, the question is would the stock rear end be stronger enought to handle the ls2 swap with out breaking the rearend. i'm running with a 373 gear, 22inch tires,not racing but plan to hit it every so often. I just dont want to spend money twice

Well i know its 10 nuts i had to take off to get to the gears, a lowrider shop told me i may be fine if i go with racing axels since they never broke a rearend with hydraulics. then i was also told if i toy around to much and hard i could snap the rearend, so i'm un-sure what i should do. I want to do something fast since i'm doing my mock up for my frame off

As an owner of one of those cars I can say the gears are strong enough for daily use but the axles are the weak spot. Using a manual transmission and a heavy foot will make for short lived axles. However behind an automatic without a heavy foot they will be fine - if the axles themselves are good in the first place.
Save yourself the stress and either replace the axles, seals and bearings with new stuff or replace the entire housing with a stronger style housing.
If you are in the lowrider scene, I know a guy who does 9" rears for Impala's ready to install with or without a wishbone. PM me for details.

yeah i know a guy at this lowrider shop who can do the ford nine 9inch, but another guy who builds motors told me that there is a 12 bolt rear end that chevy made for the impala, the problem now is me trying to find one, and would that with stand the power & really made a difference

I'm on my 2nd stock rear in my 63 2 door hardtop with a small cammed 350 stock 700r4 3.55s and 15 inch wheels. It's a DD that gets an occasionally beating on the street and hasn't been to the track in almost 2 years I'd say now and I'm fixing to replace it again. I'm ditching mine when I do it and would suggest anyone else do the same.

I'm using custom engine mounts, transmission mount and custom drive shaft with a 9" in my car. I don't know if you have looked at a factory Impala drive shaft but I have seen pencils nearly that size - after market shafts use 4" tubes. If you want to get scared do a search on drive shaft frequency and theory then measure your factory drive shaft...

Do you still have the old 3.73 Center Section. If so, is it a P case? Would you sell it?
