You should get this moved into the LS swap section. There are guys WAY smarter than I ,, including CL.. I didn't catch the aluminum block,, 5.3 iron block will go to 3.904,, the aluminum block 3.780 sleeves no way are going to take that massive overbore.

So as an option,, how about looking around for a LS-1 block. They are getting to be like the beloved Gen I SBC as in they are now appearing in a back yard near you.
