What is the difference between an H22a4 auto block to an H22a4 manual block. Will an auto block work with a manual tranny is manly what I am asking. I just bought another block but now found out that it is from an automatic prelude. I have a full h22a4 motor swap but want to know if this spare block that I bought will work if I ever need to use it.

 

The tranny type should be interchangeable between blocks. If you have an automatic LS motor, you can easily bolt a manual on before the swap and it will function the same way.

Of course, you are going to have to switch the auto flexplate for a manual flywheel, but the tranny should just bolt right on.
