[Fot] Fw: Early Block - Follow-up

[gregmogdoc at surfnetusa.com]

I have rebuilt a number of early 1950s Vanguard
engines that were fitted to Morgan +4 and recently
did a tr-2000 roadster engine that is the same and
the Vanguard.  I have never seen a block before that
has the cast water holes in the center web of the
block nor have I ever seen the a web that extends all
the way to the top surface of the block so that it
was machine flat along with the rest of the top
surface  of the block.

        Hi again, Joe.  I hadn't looked at your
pictures before I send my last note.  Now that I see
your picture, I realize that the early TR-2's did not
have bosses cast into the block for the retaining
screws for cam bearings (like my later TR-2 block
has).  So apparently, while not anticipating cam
bearings when the engine was first designed (perhaps
for tractor use), at some time durng the TR-2
production run they realized that cam bearings would
some day be required, so they made the necessary
changes to the block casting to allow later
implementation of cam bearings with only machining
changes.  Interesting.

        Hi Joe.  I have the block from my TR-2, which
had no cam bearings.  I am using a later block in the
car because I wanted cam bearings.  It is a late
TR-2, block number is 7257.  While it does not have
cam bearings, or holes for the retaining bolts, I
believe they anticipated adding cam bearings at some
time, as the bosses for the holes for the retaining
bolts are cast into the block.  I don't know if this
is true of all TR-2 blocks, but it certainly made it
easier when they added cam bearings.  No changes were
required to the block casting, only the machining was
different.  Interesting history.Jack

                Kas and All.Sean was stripping a
block and noticed that there were no Cam Bearing
Retainer Hardware. And the center web bridged the
width of the block and was machined.> >
