A12 dizzy will be right if its a late block with the dizzy in the middle otherwise its just a simple baseplate change. The radiator will be sufficient but not the best. I ran a standard radiator behine my worked 1400 and it did tend to get quite hot on the highway. Upgraded to a gemini and no more problems. Had a sunny one as well which worked well. Easier fit than the gemini. Alternator wiring will be fine again if its a late block. Will need slight rewiring if its an early block. And the last thing i can think of the a14 needs engine mount spacers to mover it back around 25mm i think(just search it). Plate steel with two holes drilled. Simple.
