My spitfire has the 1300cc engine and I have replaced the twin SU's with a single downdraft Weber.
Here are some closeup shots of the weber. I also added a header and 2 inch exhaust system.
My engine number. This indicates I have a Federal (USA) 1296cc Engine.
My Commission Number. This indicates I have a 1968 Spitfire Mk 3 that originally Royal Blue Paint and Shadow Blue interior.
When I got it, it was black with a black interior.
