I'll keep you posted once I start a build. It will probably sit in the garage for a while.

I believe these are all early 2020 engines.
@BoostedOne Did you use the LT4 injectors on any of your builds? Also do you know if the injector harness is the same for the LT2 and LT4? I appreciate any input on upgraded fueling.

I just purchased one as well, hopefully it gets here as fast as others have received theirs?

I asked the seller if these were the hurricane car motors, they are not. Sounds like they were test/bench motors that were never actually in a car?

Are you planning increased Cubic inches?

I have not used the LT4 injectors yet but I will on the next build as these stock 2020 injectors will need to go back in the car when going back to stock.

The passenger side injector harness is different as the plug for the HPFP was changed. I used an early LT4 harness to swap to an LT4 HPFP.

Nice, this is what I'm looking to do as well. Do you have any part numbers for the harness? I have all the part numbers for the LT4 fuel lines, do you know if the LT2 and LT4 fuel rails are the same?
I appreciate you sharing your knowledge on this platform.

I read something similar, as these may have been production motors.

Can you increase the displacement on these engines. I'm interested.

There's not a lot of information and/or development on the LT2, but that may be changing. LME did a 390" LT2 stroker a year ago and Katech is offering a 427 package on their website.

With any luck my motor will show up this week. For those of you who picked up one of these is it possible to turn the crank to at least confirm it’s not seized? If so anyone know the bolt size on the crank to turn it?

Yes, I was able to turn the crank. 24mm, turn it slow or the caps will fly off
