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.

 

There is no difference between those auto and standard blocks. The main difference is in the wiring, transmission, driveplate/flywheel.
