Sam is a northerner who's known in the TL community as being one of the most knowledgeable folk out there on tl engines. He's raced them, built them and even built a supercharged TL with close to 200bhp.He's also developed the most reliable big bore kits on the market for tl engines. I know of TL owners who have driven from Norway just to take their engine to Sam for it to be rebuilt. On top of that, he's a decent genuine bloke too.
