The WP Motown block is a whole different motor in comparison to the LS series'. They may use the LS heads but have the traditional SB lower end. The deep skirt LS block still looks like a problem to me. The small block pan is only there to capture and store oil and is an easy uncomplicated piece open to modification so thats a simple mod.
You'll probably have issues with the oil filter but a remote mount would be easy. Don't know how your fan will land in comparison to the 455 but a modified or new shroud may be required. Power steering and A/C lines will probably need addressing too as well as alternator and sensor wiring but nothing earth shattering. These are a fairly simple problems but would need to be addressed. The simpler the swap the more people that would attempt it. I'm certainly not the one to 'dis' this project and love that you're taking it on.
The 383 has been around for a LONG time. I have a 364" stroker in the garage I've never run. But, the Olds blocks will certainly out live the Chevy's as they were built using a higher nickel content block so, bottom line, 'you spend your money the way you feel best'. If you think gas is a better direction than diesel, go for it. I'll be watching with great interest.
