I know this is probably a stupid question for most, but please bear with me, I am trying to learn.

I have a '68 that I am slowly working on. I assume the factory sent these cars out with 8.2 axles. Correct? What are the carrier/ gear ratio cutoffs? Meaning, if you had 3.73s, what else would go on that carrier.

I have not pulled the cover to confirm the ratio. I assume it's pretty high. I was guessing around 2.73 or so, but I don't know if that's even an available ratio.

Now the fun stuff. What TQ/ HP would these rear ends be okay with? I am not building a drag car. But I expect to be around 350HP or so. Also, what limited slips, ect are recommended and what gear ratios should I really be looking at?

The car is gonna be a cruiser that will see hiway time. So, I want to keep freeway speed rpms down to an acceptable level. Te TH400 and the very mild 455 will take care of getting it moving. Again, not a wild car. Strong runner, but on cheapo unleaded.

Thanks!!
