Paul afraid to say if your engine is for a GT6 then it will be 2 litres not 2.5 litres that it should be

What are the first two characters of your engine number?

 

KC or KE is 2 litre GT6, rated around 100bhp.

 

CP or CR is 2.5 litre UK spec injected TR6, rated at about 150 and 130bhp respectively.

Just cos its got a GT engine number,

dont mean its a 2 litre,

 

My GT, KE, is 2.5, not 2.0L

 

so maybe woe ever said it were a GT engine, actually meant it were a GT comm number, thats all.

Sorry I should have qualified that comment if its a standard GT6 engine then it will be a 2 litre, but it is possible its been worked on and converted to 2.5 litre. If its a 2 litre engine the stroke will be 3" if its a 2.5Litre then it will have a 3.7" stoke have a look at https://en.wikipedia.org/wiki/Triumph_I6

The engine number just tells you what the block originally came from. What internals are in it now may well be vastly different to when it left the factory in a GT6.

 

There were a number of different blocks used but to a large extent the differences are insignificant so cranks, cams, timing gear, sumps, engine plates etc can be put into the different blocks. As has already said a 2.5 is a 2L with a longer stroke crank rather than a different bore. Swapping a crank alone would affect the compression ratio so that had to be factored in and the appropriate head and internals have to be used.
