The fronts are a go, it's been done for a while. You just need the LS1 conversion parts. As for the rears, I don't think anyone has installed LS1s on a 9 bolt rear, the bolt patterns are different and the LS1 backing plates would need major reworking to fit them on. I'd go with the LT1/1LEs on the rear.
