Not my add, I know nothing about this but I've just seen it advertised,

Engine number 6405435

Not sure if it's a genuine 914/6 motor but eBay uk has it listed for total rebuild
It's allegedly GT spec! Hmmmm I'm always cynical about these claims, and they're asking £13000 - !


If you're hunting this serial number I hope this helps that's the only reason I posted this.
