Some sources say when building an engine to paint the lifter valley and the
inside of the crankcase. Others say that once the casting flash and other
rough spots are touched up, no paint is needed. What are the opinions of list
members? And for those of you who say "paint it", does it have to be some
zillion-dollar-an-ounce titanium-zircon, or will a good coat of tractor enamel
do the job?

Hi Dick
Do both! Buzz off all the casting flash to clean it up and to reduce stress
risers in the block. I do the entire block, inside and out. The Glyptol not
only seals in any latent casting sand but it also lets oil "slide" over it
allowing the valley to drain oil back quicker. The crankcase sheds oil also
with
Glyptol. The inside of my SB2.2 block has been completely polished for
quicker oil scavenging.
If you aren't using a crank scrapper, I would take the time to fit a very
close one. Free HP by cleaning the oil off the crank. I saw a pic through a
glass window in the pan of an engine running at 6000. The oil wrapped around
the
crank like molasses!!! You would think it would just fly off but that's not
the case.
