Get some big torsion bars in there, yeah it will "work fine" with standard V8 torsion bars as long as you don't mind taking every corner at 10 MPH. I have 1.0" t-bars with an aluminum-headed 360 and plan to put in even bigger ones after upgrading other suspension stuff more. BTW the ride is actually great, shocks have the biggest effect on ride quality anyway. Never heard someone complain about a stiff ride after upgrading torsion bars; shocks, yes but t-bars not really.
I'd also say subframe connectors and rear torque boxes are pretty much mandatory with that monster 440 torque, IMO at least.
