Rather than removing teeth marks from the
pin, take advantage of them. They'll help
secure the pin in the new cam. So install
the pin end-for-end by driving it into place
with a punch and hammer. When it bottoms,
it's installed.
range shown in the chart, you'll obviously
use standard bearings. However, if they
mike some amount less, you'll need the
same amount of undersize bearing as the
difference from the standard nominal
bearing size. Simply put, if a 351C mainbearing
journal mikes 2.7478 inches, the
proper undersize bearing to use is 2.788
- 2.7478 = 0.010-inch undersize. So, to
determine if and how much of an undersize
bearing you need, subtract the diameter
of your bearing journals from the
standard nominal bearing-journal diameter.
There are two types of rear-main bearing
seals you can install: the rope and the
split-lip types. A rope seal will probably
be included in your gasket set. It consists
of two pieces of graphite-impregnated
rope. The split-lip seal is made from neoprene,
also in two pieces. If you want this
seal instead of the rope type, you'll have
to lay out another three bucks or so. I
like the split-lip seal because a rope seal
is more difficult to install. And, the rope
seal creates more friction, as initially
installed, meaning the torque required to
turn the crank during assembly will
be approximately 10 ft. lbs. more.
However, the relative effectiveness of
the two seals is the same. Also, the
rope seal's initial friction drops off
considerably after the first few minutes
of engine operation.
Install the Main-Bearing Inserts-With the
engine block upside down, wipe the bearing
bores clean so there won't be any dirt
trapped behind the bearing inserts. Wipe
them clean using paper towels and a
Before installing the camshaft, apply a coat of moly-disulphide (MoS,) to the lobes. Don't
skimp here. Put moly on the cam bearings too.
Install cam by feeding it through one bearing web at a time. Challenge is to avoid bumping
the bearing inserts so they don't get damaged. Control camshaft when installing it by
using the loosely Installed drive sprocket. Your cam should rotate easily once installed.
Here's how to install a camshaft If your
crankshaft is already in place. Feed it in
from the front while supporting it with the
sprocket. Set the engine on its rear face to
make It easier. You'll then have better control
of the cam and gravity will be working
for, not against you.

Bluing and scraping cam bearings-the
thing I warned you about possibly having to
do. I'm doing the front one here. Center
three are tough to do. This is a job for an
expert.
