Can I Swap an SC400 longblock for an LS400 longblock?

I was originally gonna rebuild my 92 SC400 1UZ to swap into my 87 supra and after thinking long and hard, but I have decided not to open up my 1UZ and swap it in as is. I really just want to get this project started. As far as parts, all i really need now is a manual conversion kit to match my W58.

So In time (after my swap is completed of course) I will buy an 89-94 LS400 longblock from a local junkyard for less than $200 and use that as my foundation for my future rebuild project.

The only differences between the 2 motors other than the oil pans are the hydraulic fan for the SC, and the LS uses a fan driven by a pulley right?

So will replacing an SC400 longblock with one from an LS400 change anything??? :confused:

I just want to make sure everything from the SC400 motor with bolt on the the LS motor in the future without any problems

yes the long blocks are identical, as you said oil pan differences and hydro fan differences but those will all swap over
