Basically, you need to swap EVERYTHING attached to the basic block from the 89 engine (even the front cover and OMP) onto the 88 block, and block off the EGR valve. I think there might be a tiny bit of grinding on the block to get it to fit, but I cant remember. There is a full writeup on www.rotaryresurrection.com in the tech section.
