Interchangeability of FE to EJ motor parts

[Rodger]

Hello, I have a fully rebuilt FE numbered motor (in an FC).  Post rebuild have discovered a crack in the block between 1 and 2 (front) exhaust outlet.  Not yet determined how repairable.  The FE block is bored to 138 with new STD pistons.  Otherwise the motor is stock but refurbished.  If on inspection I require a new block I have access to an EJ and an FB numbered motor.  My question is, 'Are those EJ and FB motor innards (block) able to receive the refurbished parts from my FE motor fully?'  E.g. transferable crank, heads mate etc.

Thank you, Rodger
