Default SBC to LS Length

Does anyone know the difference in the rear of the block between L92 and a SBC. I’ll be using ICT mounts to keep the engine in neutral position but I’ve heard the rear of LS blocks are shorter and I want my shifter to come out of the floor in the same location.

Id bolt the trans to a mock-up block and set it in with the new mounts. Make sure the trans mount is in place and snug it down, and then see how the ICT engine mounts line up….mod if necessary. That’s the only sure way to have the trans in the same spot.

If there is a difference it's not very much. I went from a 350sbc/T56 to an LS1/T56 in my car years ago and the shifter ended up in about the same spot.

SBC block length is 21.78"
LS block length is 20.43" (519mm)

that is purely the block, and not the overall engine assembly.
