Okay, take the engine out of a Puma and put it in a Spitfire chassis you say. Half a day's work maybe?
No. How about two days just to remove the fuel tank due to the very rusty state of everything on this seventeen year old Ford. Everything's seized, 'quick release' fasteners just won't and everything breaks when you try to force it.
And then you find that the tank is looking too rusty to use anyway as some of the metal feels awfully thin to me.
But, new Puma tanks are cheap so I started to disconnect all the ancillaries and connectors from the engine. Lots and lots of connectors. Which is when I realised that this modern engine is just too complicated for what I want. Even if I could get it installed and running, if it ever broke down I wouldn't have a clue how to fix it.
So, the Puma's off to the scrappy and the gearbox and adaptor are for sale and Plan B it is.
£200 takes it all away.
