Looks like an older thread but my 420whp LS6 Datsun had Tokico blues, coil over sleeves and 225f 250r 10" eibach springs. I tracked it and ran it through the canyons quite a bit and loved it. I recently just swapped to P30-0032 bilsteins with sectioned strut tubes and camber plates and it still feels great. My engine is lighter than the stock 2.8 that was in there so not sure how this translates for any heavier V8 swaps and how they manage extra weight if any. I would assume mainly heavier/stronger springs for starters.
