Just rebuilt the bottom end, cranked the engine round and the pistons protude above the block face by about 2 - 3 mm.

Each one is the same, there has been NO change of the crank, conrods or pistons.

Is this meant to happen?? i cant remember when i took the engine apart.

The only reason i ask is that i thought they were meant to be low compression engines and surely this would make them alot higher??

any help much appreciated.
