I'm going to build up a new blower motor using an LS6 block. Now I'm wondering if there are any LS1 parts that will not work in the block or are they all interchangable? Like crankshaft, bearings, gaskets, head stud kit....does anything for the LS1 not work on or in the LS6 block? All I know is that the LS6 has the better internal vents and its a stronger aluminum. Anything I should know before ordering the parts? Thanks

AFAIK, they are 100% interchangeable.

 

There might be a little difference in the dip stick tube and location. Not sure.
