Santa Came A Little Early

392 4.06X3.79 No2 engine

It has "Finished" bores in it at 4.040", but it also has a spread of .003" from cylinder to cylinder, and most of them have way to much taper and out of round for my taste. Typical MP work. Plus we have to machine all the "extra" head bolt bosses out to make room for headers/roller lifters.
