CKD South African built Sunbeam Tiger

[crk]

Good morning from N Wales UK, in 1994 a Sunbeam Tiger came to the UK,I bought it in 2004,it has on its reg document 289 engine, I have often wondered if any history about in SA (have no SA reg number),I started to look the engine numbers recently, discovered D20E-6015-AB which is a 302,also the reg document records the engine number as 386 which is odd, it has an alloy high rise manifold, and was told it was bought to uk with "hotter cams". The Tiger has had modification to panel ,under the bumper to aid cooling, it was originally white now red
Could this engine have come from a Ford Capri V8 Perana??
I know this is a massive shot in the dark, but would be very grateful for any thoughts/history etc
All the best
Colin
