GEN III parts in GEN V engine This is a question for the internal engine experts that have worked with the new GEN V engine.
Aside from a reluctor wheel change if a 24 tooth wheel, can the GEN III crankshaft work in the new GEN V engine?
What about GEN III connecting rods?
If not, what are the differences?

Yea im sure it can. Only diference that o know of is the rods and reluctor. Blocks are the same. O yea knock sensor on the gen 4 are on the side of the block rather than top under valley cover. And the gen 4 has a cam sensor in the front timing cover. The gen 3 is on the side. But all u need to do is swap crank and rods from gen 3 to gen 4 engine. Use gen 4 cam gear or purchase the linkenfelter cam gear that allows u to use a 3 bolt cam swap. And just exstend knock sensor harness pigtails. Pretty straight forward swap.

Pretty sure that they are vastly different than the previous 2 gens which were very interchangeable.

would bet that most of the internals work just fine.
a close look at the GenV seems to show that the block is an evolution not a revolution.
same deep skirt 6 bolt mains, the rods are the same length as most LS1 aftermarket rods (6.125"), same bore as the LS3,A, and 9. same reluctor wheel as the late LS series?
The VVT system will probably be slightly different, the cam gear will probably be similar or identical.

The best answer is no
there are a few things that can be shared, but most cannot.
The camshafts cannot be shared due to the direct injection and the reverse intake and exhaust feature of the head.
The crankshafts snout radius is different, as well as the how the flexplate/flywheel bolts
Rods are interchangeable, but pistons would need to be modified to work due to the oiling.
There is no way as of yet to remove the VVT from the LT1.
Heads of course are completley different
There are a few more differences, but nothing else major.

I still need to find a buyer for my parts which are nice, and in the for sale section, and then move forward from there.

Pistons won't work for sure. Intake and exhaust valves have been swapped on the Gen V, (meaning exhaust valve is where the intake valve is on Gen3 and Gen 4). They are also domed slightly, vs flat tops in the LS engines.
If you want to upgrade crank/rods/pistons over stockers? Get yourself into some quality aftermarkets parts like callies crank with H beam rods and some wisecos or Diamond pistons etc. Give yourself a bit of stroke and maybe bore and add cubes while your at it. IMO not worth a moment of time trying to swap stock GENV internals into a GENIV block.
Besides... the stock GENIV internals are STOUT! Mine have seen many, many romps to 8000RPM and a couple over 9k ( one piston to valve issue ) but no serious piston damage so im still running the 100% OEM genIV short. Its been stellar
