Correct. You can convert a GT6 engine to 2500cc by using a
TR6 crank and pistons. According to the information I have,
the rods and block (within the commission numbers listed
above) are the same. You just have to
be careful not to use the wrong head with the wrong pistons
or you will end up with a very high or very low compression
ratio. Note that the GT6 flywheel will only work with later
TR6 cranks. All things considered, it would probably be
easier to just use a complete TR6 engine. If you want to
put a 2500 in a GT6, you need a GT6/Vitesse oil pan and a
crank that is compatible with the GT6 flywheel. And probably
a good supply of extra differentials, but that's another
story in itself.
