The 3.1 in the Cavalier '07-10, '13-20 has about 500hrs on it now, still going strong.
The LZ9 (2006-2010, Monte Carlo/Impala/Malibu/Uplander) is 350lb of 3.9 liter power: 240HP/240FT LB, more than 200 ft lb from 1800RPM-5200RPM, variable cam timing.
Don't get the LZG/LZ8 DOD(displacement on demand) version. I have the software to burn a standalone PCM that uses Trailblazer code to take out the Body Control Module and security stuff, as well as triggering the starter correctly. This will also work with the LZ4 3.5 (same 99mm bore). The best part is that they are $350-600 all day and they made something like 500000 of the 3.5/3.9s from '06-'10.
FWD, bolt it up to a Muncie/Getrag 282 ('86-'94) or a Getrag F23 (a couple years of later Cavalier) Get the halfshaft extension for equal length.
RWD, bolt it up to an AX15 out of an '89-'96 Dodge Dakota or similar year 2wd Jeep Cherokee that originally had the 2.5 AMC motor.
What shape is the oilpan? Are there different factory options? I have had to get an Ecotec pan cut and welded to avoid the steering rack in the 280 ZX as the FWD options tend not to have traditional RWD front or back clearances.
A V6 would fit nicely in there if I could avoid the rack.
The oil pan is an alloy casting for block rigidity - it's a FWD application that ends up rear sump in longitudinal mode. I don't think there are any variations. The 'cut' is about 6 inches from the front of the motor.
A regular RWD application should be doable, I know 3rd and 4th gen Camaro owners have been swapping their 2.8, 3.1, and 3.4 V6s for the much better 3400, 3500, and 3900 engines. So, there is precedent for them working in at least some RWD applications. F-body people have it easy, they're working with a vehicle that already came with a 60degree V6, and in a much wider car, but who knows, you may get lucky too. Oil pans from other 60degree engines may work, but there were some differences in block over the years, especially depending on application, so, proceed with caution.
