Lotus Twincam Big valve Weber head. Rebuilt to original factory quality specs. This engine was originaly from a +2S130. It was rebuilt in England by a factory mechanic. It has the "L" block and the "N" stamped on the head showing it originaly was a Big Valve. It also has the "D" cams. The carburettors are Dellorto DHLA 40. The engine was recently rebuilt with new gaskits and seals and water pump. It has properly been runin. This engine includes a distributor and includes a fuel pump. The price also includes a 4-2-1 headers. I'm selling because I bought it as a spare engine and decided I'll never use it.
