Best Diff for 600-700hp?

[yody]

it really depends on what you are going to do with the car, if you never plan to put slicks on it, or do high rpm clutch dumps, then you can get away with a less beefy rearend. I probably have 630hp or something like that, at least 600 and am only running a 8.5 ten bolt, with 30 spline posi, moser axles and U.S gears with a rearend girdle cover. I don't plan on much drag racing and think this rearend should last a long time. Its also lighter and cheaper than a lot others, there are guys with spools and 8.5's running 9's

No slicks (well, drag radials ), no high RPM launches. I will drag race it a bit, but not a lot. Mostly cruising around town. I'm going to be running (probably) a 9" from DTS w/ a nodular strange housing and the likes. DTS uses, amoung others, Strange parts and they are cheaper than the other companies direct. I got a quote in the $2150 area where Moser and Strange wanted $2300-2350. My weak link is going to be my transmission, I would think. I have a local guy who will guarantee (I know that many people here would contest this number) his 700R4 for 700hp for $1200. Can't go wrong with that number (as compared to $4k for a 4L80E).

As for higher hp (than 600-650), I just need it to hold up for a couple dyno pulls if I spring for the D-1SC, because, where the hell am I going to use 800hp on the street ?

Thanks for the imput Yody.
