cheapest swap would be the LT1. LT1's are cheaper, cheaper to tune, won't require any special motor mounts. The LT1 is your basic small block, so a lot of parts-headers, radiator ect. can be re-used or found for cheap.
LS1-better all around motor in my opinion. Cost will be greater to swap. Also LS1's put up better MPG than most LT1's, so if it is your daily driver, it could be cost beneficial in the long run.
With the LS1 you will need a Radiator, motor mounts, headers, tune, wiring harness, crossmember for 4l60e. There is probably a few other things that I am not thinking of.
Hope this helps.

I have a complete bolt in setup (LT1/4l60E) that is perfect for a first gen camaro/3rd gen nova. When I say complete bolt in, the only thing missing is the fuel system (tank and lines). I am getting ready to do a L92 swap. PM me if you want details.

If I were to do it over again, I'd go with a LSx. Way more aftermarket support, and the heads are much better than the LT1.
Why did I go with the LT1? I had a good one sitting around. Famous last words!
The few, the proud, the crazy... the LT1 owners.

There is a lot to be said for the "bolt-upness" of the LT1. It's basically drop in with a new ECM.
But if I was gonna do an LT1, I'd probably go with a traditional smallblock with a TPI based setup. Buy a ZZ383 and install an Accel DFI setup on it1971 Camaro, 383 stroker ~500HP,M21 Trans with lightened flywheel. All Sorts of Auto-x Goodness in the Suspension. 12" Brakes ->SOLD
