8 3/4 tough enough?

Hi Guys,

Looking to build a rear end for my 69 Barracuda and wondering if an 8 3/4 diff will be reliable enough if fitted with 30 spline axles and a tru trac centre / 3.9 gears.

I don't have an 8 3/4 housing to suit and would have to shorten a b or e body housing out here which are more common out here in Australia and would have to ship most of the parts over.

Car will have around 600 flywheek hp hopefully once I get the W5 heads ported and fit a bigger cam into my 408 stroker (currently w2 heads). Car has a CRT 727 fitted.

Car wont be drag only and will see a lot of street miles but it will cop a set of slicks occasionally and don't want to invest a lot of money into something that may break at the drags?

Any advice appreciated.

Thanks
