I ordered my LS3 with the same reluctor wheel as an LS1/6, from LME. It works great, you will also need to order an adaptor cable. Pretty simple ,as long as the +12 and ground are not reversed in the cable, as mine was.

I was thinking if my LS1 ever calved on me I would go for an LS6 so that I wouldn't have to buy a bunch of addional smaller parts to make it work. Or better yet an LS6 shortblock with some decent aftermarket heads.

I have been thinking about this sort of a swap for a while. If it was basically stock how much did it run you? How complete was it and how much of the LS1 peripherals worked? The LS3 has the different style injectors right? Are the engine electronics compatible?

I do not recall the price for the short block, however I thought it to be a good price for quality parts and labor.

I think it would be a cost effective way to go considering you can sell your old engine for some cash too. Lot of hot rod guys like the LS1 for builds. Would cost less than a turbocharger or supercharger and probably a good set of heads and a cam with labor.
And a new crate is under warrantee.

We have been doing LS3 conversions with the electrical cross over boxes from LPE, they work great. Good luck with your build!

I see alot more guys looking at the LS3 convertion. Maybe you can write up all the little parts they need to order, and about how much in a big ball park range ECS would charge for the swap.
Im selfish. When my motor goes, that's the direction im looking at also.

to answer your question on what my goals are.
since i have over 100k on the motor and trans, i think that i will add to much eventually to my old LS1. The problem is that i always will want more! so my goal now will change when i get used to the mods that i have made.
LS3 swap gives a warranty, and more room to build on later

Going to need new Muffler bearings as well, and the canooter valve has a completly different tune for the LS3 that it does on the LS1..
