connecting rods clear correctly?
It depends. I had no clearance problems when I built my 3.1 liter, but other people have. The diameter of the bore is a factor, a 89mm diameter bore will give you more clearance than a 87mm bore. The 9mm connecting rods have less clearance than the 8mm rods. And there are probably slight differences in the L28 block due to tolerances and changes to the casting molds during the production run of the L28. So, you must expect to check this during engine assembly and take appropriate measures if necessary (get the die grinder out).
