Anyone install the LS3 motor in a LS1 bay

So we've moved from the LS2 to the LS3 with 430 HP

Does it drop in with the same issues and the LS2?

What's needed for the change over

Reluctor wheel swap or use a 2005 or earlier crank.

I installed a ls3 setup in my cts-v. That main thing is the rel. wheel swap. Other than that everything was great. She makes 425rwhp though stock manifolds & exhaust. I cnc'd the heads & put a 217/220 camshaft in
