Can i put a rover 414 engine in it

you really need to get a later engine as the engines are slightly different and less hassle,the main differences are the ignition system and sump pan,the 414 engine will have distributor and leads ignition sysytem where the 25 will have plugtop coil packs,the 414 will have steel sump instead of the alloy sump on the 25,the flywheel will be different as well as the wiring loom
