[TR] TR Engine Blocks

[John Macartney]

Can't really see the point of reboring an old sleeve - though it can be done.
Best option is to obtain a matching piston and sleeve set with all the
necessary 
seals. That way you can take a 1991cc engine up to 2138cc. Don't
know their 
availability in the US - but no problem in the UK. Would be
surprised if the 
block is damaged unless it froze over many times during
storage. Those blocks 
can take some 'hammer' - even at -40deg and no
anti-freeze

General restoration
question:  

I first found my "barnfind" '59 TR3A in a shed in Osinnee, NY for
$500 back in 
about 2001.  It had sat there since 1975.

It was a $500 car, no
question.

Anyway, it was so rusty, the only reason I wound up taking a chance
on the frame 
being solid was a) you could get all the parts for it, but also
b) I found out 
it had wetliners, so the car could be 100% restored to new
(except for the 
crank).

Question:  Most antique LBCs, like MGA's, anyway,had
solid blocks.  You can bore 
them to what, .003 over before running into
trouble with too thin walls?  So 
what do restorers do with cars they pick up,
begin a restoration, and find the 
block is shot.  Are there aftermarket new
blocks, or do machines put in somekind 
of custome sleeve to build the
cylinder back up?

Just curious.
