After the ring is squared in the bore,
you use a feeler gage to check your progress. I used a .014" and
.018" which is shown in the picture below. The reason for the
smaller size (.014") is so I would know when I was getting close
and could be careful sneaking up on the final size.

This is what it looks like when the
gap is done. Believe it or not, this is .018". Now I marked this
ring with a felt-marker with a "number 1" to make sure it goes
on the corresponding piston. This is done for each cylinder. After all
the top rings were done, it was time to do the "second rings".
The second ring has a smaller gap of .0145" minimum. I made these
.016" and then marked them like the top ones. Doing this takes
awhile but it's worth some extra horsepower in the end.

Time to install the
cam bearings. Dart provides these when you buy the block. Dart also
makes ALL the cam bearings the same size unlike General Motors that has
more than one size. I think GM should take a page from these guys and do
the same thing. Notice the
groove that goes all the way around it along with the three oiling
holes. This means that you don't have to align the hole in the bearings
with the holes in the block. This is another good thing that Dart
does.

The cam bearings go into those holes
under the mains. The bearings have a press-fit and you have to use a
special tool to install them. Let's get the tool out and get busy.
