[TR] TR Engine Blocks

[wbeech at flash.net]

John,
Is the 2138cc you quote using 86mm or 87mm pistons and sleeves?  And yes,
they are readily available in the US.
Thx,
Bill

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.
