I know there are a few parts that need to be changed on the LSx engines if you want to use an older T56.

I don't know why.

Here is a guy who bolted a T10 an LSx, why can't the same "procedure" be done for an older T56?

you can bolt the lt1 t56, but the ls t56 is generally better and has a better clutch/hydraullics design.

Input shaft length/clutch styles are completely different. That's the primary issue. The Clutch on a LTx motor is unique as it pulls on the pressure plate instead of pushes on it; this is why it's not as simple as a T-10, M2x, Richmond, etc swap on a LS motor.

The lt1 uses a 153 tooth flywheel. The ls1, and alot of sbc style trans use a 168 tooth flywheel. THe larger flywheel will not fit in the lt1 bell. you could get a custom flywheel, but they are expensive. Cheaper to convert or sell an lt1 trans and buy an ls trans.

So it would probably be easier to put an LSx T56 on a SBC or BBC than an LT1 T56?
