It would require a complete retune and either a reluctor swap or an adapter box from lingenfelter.

It will run, I did it. You'll need your Ls1 knock sensors bolted to the side of the block, one on each side. Map sensor extension, cam sensor extension but this harness comes with the knock sensor extensions. Other than that the Ls3 has 58xtooth reluctor wheel for the crank sensor and the Ls1 has 24x tooth so that why you'll need the LPE converter box. You'll also need to convert the timing gear to a 3 bolt cam sprocket and put a 4x bump on it. LPE' web site has all that info that's pretty useful.
