I have an Ls1 5.7, forged bottom end, profiler heads 300 cfm (215cc), fast 90 intake, 232/236 cam, it has some nice parts to make the LS1 really open up. Should be around 500 hp......Will be a Street car mostly, occasional autocross, track days.

That's cheap...but may not save you much if you end up replacing or modifying everything. Given your engine build, you'll want alloy 31-spline axles minimum, however going 35-spline will require an aftermarket diff housing. I'm not a big fan of the Trac-Lock myself, 2 or 4-spider, however a Detroit True-Trac could hold up with ~450-ish RWHP and shouldn't have the wear issues associated with a clutch type limited slip or the tendency to break the carrier like the True-Trac's.
It's certainly a good enough deal that you'll come out okay even if you don't use it and just sell it down the road, otherwise I'd probably look for a later 1979-1986 F-150 or E-150 9" with 31-spline axles, SET20 axle bearings and the larger 3.062" carrier bearings. These were commonly supplied with 3.50 gears and 4-spider Trac-locks...sometimes pre-broken for your convenience.
