1500 Cam - issue resolved!

["Mostrom, Paul" <Mostrom.Paul@principal.com>]

I called the machine shop again this morning and found out that what we had
was a 'failure to communicate'.  They thought there was a babbeted or
pressed-in bearing in the block, which would get ruined by the hot-tanking
process.  Since the cam runs on the cast iron, hot-tanking will not damage a
bearing, and the cam journals fit good in the block so we will not be
line-boring the block and putting bearings in it. 

Sorry for any confusion, and thanks for all your input.
